We're into the final 36 hours of the summer transfer window, with Championship clubs still working hard to add to their squads.

Middlesbrough and Sunderland look set for a busy close to the window, but what about their rivals. Here's a rundown of what to expect from every Championship club:

BIRMINGHAM CITY

Alex Dicken, Birmingham Mail

Birmingham City have been among the busiest Championship clubs in the transfer window. They got off to a quickfire start by making five signings before the end of June and lots more have followed since. 

Blues are looking to fine-tune their high-flying squad before the deadline with some defensive additions. A new centre-back is the priority, with the possibility of a right-back too.

There could be a couple of departures with Sam Cosgrove expected to be the most high profile of them. League One clubs have shown interest in him. 

Youngsters such as Josh Williams could be allowed out on loan, although Blues need to be mindful to not leave themselves short.  

BLACKBURN ROVERS

Elliott Jackson, Lancashire Live

Blackburn are in desperate need of some more reinforcements. Jon Dahl Tomasson has not been shy about his disappointment at the lack of movement in recent weeks. Goalkeeper Leopold Wahlstedt was the only signing since the end of June prior to Andy Moran joining from Brighton last weekend.

A striker has been the number one priority all summer and it's something Rovers are trying to address. The loan market seems the most likely avenue for that given their limited resources at the moment.

Centre-back is a priority too, with the exits of Daniel Ayala (released), Ash Phillips (Tottenham) and injury to Sam Barnes leaving them with three senior CBs. Danny Batth has been heavily linked but there are concerns about committing to an ageing player on any more than a one-year deal.

BRISTOL CITY

James Piercy, Bristol Live

There is irritation within the fanbase that despite an encouraging window, City won't be recruiting a central striker or goalkeeper to challenge No.1 Max O'Leary. 

This essentially stems from the slight bewilderment over the fact very little of the £25m sale of Alex Scott will be immediately reinvested into the team due to an internal wage ceiling that Nigel Pearson insists they've hit, hence the lack of flexibility to do any further business. 

In terms of outgoings there will be a few loans for some of the younger talent, although many will also be kept in-house to help cover any depth issues. 

The one player that could cause some concern is Zak Vyner; the centre-back is a nailed-on starter but is out of contract in 12 months and has interest across the Championship. Contract talks don't seem to have progressed so City are vulnerable to late bids and Pearson would be very, very annoyed to see any kind of sale sanctioned.

CARDIFF CITY

Glen Williams, WalesOnline

It's been one of the best windows Bluebirds supporters can remember for some time. The return of the prodigal son, Aaron Ramsey, coupled with some shrewd forward additions such as Karlan Grant and Josh Bowler has made for an exciting window, but Cardiff have hardly shot out of the blocks.

Their defence looks a little light and I would be gobsmacked if another centre-back isn't through the door before the window closes. While, at the top end of the pitch, there is a feeling that City need a goalscorer if they have any designs on troubling the top half of the table. Although, being under an embargo and with four loan players already in, they might have to make do with only one of the two.

Outgoings are needed, too, to free up some cash. Cardiff have signed eight players at the time of writing and only really shipped out four or five senior players. Goalkeeper Ryan Allsop, midfielders Andy Rinomhota and Romaine Sawyers and winger Kieron Evans could all yet depart.

COVENTRY CITY

Andy Turner, CoventryLive/Coventry Telegraph

It’s been a huge transfer window for the Sky Blues and manager Mark Robins who has effectively rebuilt his squad following the departures of 13 senior players, including five loans and the sale of the club’s two star men, leading scorer Viktor Gyokeres (£20m to Sporting Lisbon) and superb midfielder Gustavo Hamer (£15m to Sheffield United). 

However, the combined transfer fees of those two, coupled with an incredible club record uptake of almost 19,000 season tickets, has provided the manager with a significant war chest. 

So far City have signed ten players, including paying out a club record transfer on USA international striker Haji Wright for £7.7m. Robins says that he’d still like two more if possible, with a centre-half and dynamic midfielder top of his list. 

In terms of out-goings, development midfielder Ryan Howley could go on loan while third choice goalkeeper Simon Moore is a strong possibility to move on following the arrival of Brad Collins from Barnsley.

HUDDERSFIELD TOWN

Steve Chicken, YorkshireLive

Huddersfield have been quite open all summer about the need for new recruits in attack and midfield, but made a slower start to the window than they or their fans would ideally have liked. 

Back-up goalkeeper Chris Maxwell and Stoke right-back Tom Edwards (on loan) were the only signings completed before the season began - sensible business, but not ones to get the pulse racing.

Skilful forward Delano Burgzorg has since arrived on loan from Mainz, though, and the club spent (by their own standards) a substantial transfer fee to get midfielder Ben Wiles from Rotherham. Neil Warnock still wants another option at centre-forward - possibly a big target man type - but whether they'll find someone suitable is another matter.

The club have done a lot of business on the other side of the ledger with plenty of fringe players leaving either permanently or on loan, so there isn't a huge amount more fat-trimming to be done at this stage. So far they are yet to lose any of their most important players, but you wonder if a Premier League side might be tempted by a late move for goalkeeper Lee Nicholls despite his uncharacteristically error-strewn start to the season.

HULL CITY

Barry Cooper, Hull Daily Mail

The final week promises to be a captivating watch for Hull City supporters, who have already seen Ruben Vinagre, Jason Lokilo, Liam Delap, Aaron Connolly and Scott Twine arrive. 

The club are on the cusp of signing Jaden Philogene from Aston Villa, but look set to miss out on Keinan Davis.

Liam Rosenior could yet bring in as many as three more before the 11pm deadline with a goalkeeper, midfielder and winger still on the shopping list, though the midfielder won't be Max Bird after the Derby County man sustained ankle ligament damage, ruling him out for a couple of months.

As fascinating as it is to see what happens in terms of strengthening what already looks a very good and capable Championship squad, those who depart will also attract no shortage of interest. Rosenior needs to offload as many as five players and that will be just as important in the closing hours.

IPSWICH TOWN

Stuart Watson, East Anglian Daily Times

It's been a solid, if not spectacular window for Ipswich thus far given the spending power of their American owners. A well-drilled promotion-winning team has maintained momentum, getting off to the perfect start, but both chief executive Mark Ashton and manager Kieran McKenna have insisted they still want to add 'two or three quality signings'. 

The first of those additions arrived last week in the form of versatile full-back Brandon Williams from Manchester United. A centre-back, winger and striker could still be on the shopping list. 

The only players leaving will be one or two fringe men, like Kyle Edwards, plus some youngsters on loan.

LEEDS UNITED

William Jackson, Leeds Live

It’s fair to say this summer has been challenging at Elland Road. The Whites have seen 14 players leave, including some key names, and there’s been the recent saga surrounding Wilfried Gnonto and Luis Sinisterra. 

They know they need to be busy, then, over the last week or so and are expected to be with another four or five arrivals being targeted. Former Boro defender Djed Spence arrived this week.

Daniel Farke’s side are crying out for a striker and a number 10 to give themselves an attacking edge, while reinforcements in the middle and at the back wouldn’t go amiss either.

LEICESTER CITY

Jordan Blackwell, Leicester Mercury

Following relegation and with eight players leaving on free transfers, there were always likely to be big changes to the Leicester squad this summer. 

They've broadly done a good job at revitalising the squad, bringing in two England internationals in Conor Coady and Harry Winks, using the loan market well to sign Callum Doyle and Cesare Casadei, while bringing a few more talents from overseas too. The James Maddison and Harvey Barnes money has been put to decent use.

But going into the final week of the window, there is still plenty for them to do. They want another wide-man and a defender, while they also have to get Victor Kristiansen, Harry Souttar, Patson Daka, Boubakary Soumare, Danny Ward, and Daniel Iversen out of the door. Then, if they decide to accept any bids for Jannik Vestergaard, Wilfred Ndidi, Dennis Praet, or Kelechi Iheanacho – all in the final years of their deals – they will need to dip into the market to find replacements.

MIDDLESBROUGH

Dominic Shaw, The Northern Echo

Middlesbrough have already made nine signings so far this summer, but want three more in the final week as they continue their rebuild after last season’s near miss. 

Boro have been forced into something of an overhaul after losing star loan players from last season such as Cameron Archer, Aaron Ramsey and Ryan Giles, as well as selling the Championship’s Player of the Season Chuba Akpom to Ajax.

Sam Greenwood is set to arrive on loan from Leeds, and he'll be followed by Lewis O'Brien from Nottingham Forest. Boro are also continuing their efforts to sign a striker. Midfielder Martin Payero is leaving for Udinese.

The Northern Echo: Michael Carrick at Bolton

MILLWALL

Alex Grace, South London Press

It’s been a solid window for Millwall. They have added in each department: Joe Bryan and Brooke Norton-Cuffy in defence, Sarkic in goal, plus the arrivals of Casper are Norre and Kevin Nibset for decent fees means the Lions have not cut corners in their summer recruitment. 

Gary Rowett has managed to move on some fringe players such as Tyler Burey. Jake Cooper’s future has been settled with him agreeing a new deal last week. It also looks likely the Lions will retain the services of key man Zian Flemming until January at least.

Overall, I’d say Rowett will be looking to add this week as the squad still looks thin should injures and suspensions take hold. Fans will say they still need to add in defence with the centre-back options limited.

NORWICH CITY

Paddy Davitt, Pinkun

David Wagner had announced on more than one occasion in recent weeks he was done as far as additions to the Canaries’ senior squad. But the opportunity to bring in Adam Forshaw on a free was too good to resist in recent days. 

Forshaw fits the dominant pattern underpinning City’s summer recruitment, with experience added in the form of Ashley Barnes and Shane Duffy. 

Wagner also opted for a reunion with Swiss international winger Christian Fassnacht, who he worked with at Young Boys. Spanish winger Borja Sainz is the exception to the general rule with Norwich astutely taking advantage of a relegation clause in the youngster’s deal at former Turkish Super Lig club Giresunspor. 

The transfer focus now rests on potential outs, with centre back Andrew Omobamidele linked with AC Milan and Crystal Palace. Beyond that expect some housekeeping involving potential loan exits for youngsters.

PLYMOUTH ARGYLE

Chris Errington, The Herald/Plymouth Live

Argyle did most of their transfer business before a ball was kicked in EFL action, with eight new arrivals during the summer. 

The two high-profile ones were Morgan Whittaker and Bali Mumba, joint £1 million club record signings from Swansea City and Norwich City respectively after their hugely successful loan spells with the Pilgrims last term. 

Wolves midfielder Luke Cundle arrived on a season-long loan two days after the Championship campaign began and now all that is left for Steven Schumacher to add to his squad is a striker. 

With only Ryan Hardie and Ben Waine currently at the club as forwards it is a key area to be addressed before the deadline.

PRESTON NORTH END

George Hodgson, Lancashire Post

It's a vital final few days for PNE in the transfer window, as manager Ryan Lowe looks to bolster his attack and squad depth at Deepdale. 

North End have been looking to bring Tom Cannon back on loan from Everton all summer, after last season's loan success for the Toffees man. 

However, confidence has plummeted in recent days and Preston are now having to explore alternatives - which could see PNE bring in up to three attacking players before close of play on Friday. 

North End have made six signings as things stand and things have started well on the pitch, but it's crucial that the Lilywhites strengthen further. 

On the outgoing front, no major business is expected unless decent offers were to come in for some of Preston's main assets. Youngsters heading out on loan should be PNE's lot.

QPR

David McIntyre, West London Sport

QPR are struggling to comply with Financial Fair Play rules, although Gareth Ainsworth has been able to sign his top target in Jack Colback, who has added some bite in midfield and scored on his full debut at Southampton.

The Rangers boss wants a right-back, a forward and potentially another midfielder ahead of the deadline. A number of potential loan deals are being looked at.

Striker Lyndon Dykes' recent absence with a knee injury has underlined the lack of attacking options. It has left 20-year-old Sinclair Armstrong as the main forward and led to teenager Rayan Kolli also being involved.

Selling Ilias Chair, who is expected to attract interest this week, could bring in some much-needed funds and enable Ainsworth to spend money. So too would a big-money sale of Ebere Eze by Crystal Palace - Rangers have a 20% sell-on clause as part of the deal which saw him join the Eagles. 

ROTHERHAM UNITED

Paul Davis. Rotherham Advertiser

A centre-forward, a wide man and a centre-half...

The Millers' recruitment this summer has been good but they still have three holes to fill as they look to apply the finishing touches to a squad they hope is capable of building on last term's survival feat.

The sale of midfielder Ben Wiles to Huddersfield Town has freed up some money and Rotherham are looking to generate further finance by letting some players leave.

They intend to be aggressive between now and Friday's 11pm deadline.

SHEFFIELD WEDNESDAY

Ricky Charlesworth, Yorkshire Live

After an extremely slow start to the window Wednesday have gone into overdrive. Ten new signings have arrived in less than a month and integrating them into the existing squad has proved an issue.

Manager Xisco Munoz admits they are playing catch up but he's hopeful of a couple more additions before the window shuts. Another midfielder to fill the void of the injured Momo Diaby looks a safe bet. A new left-back too, perhaps.

Outgoings-wise, expect a clutch of youngsters to be loaned out with potentially one or two senior players attracting interest from elsewhere in the EFL.

SOUTHAMPTON

Mark Wyatt, HampshireLive 

It was always going to be a busy window for Saints following relegation and, as expected, they've seen some big names leave the club for big fees. 

The club have raked in well over £100million and have had a solid start to the Championship season so far, but they still have work to do. A centre-back, wide forward and a striker are all being targeted, with the latter likely to replace Che Adams if he secures an exit. Sunderland's Ross Stewart is Southampton's top target.

There are still question marks over the futures of Nathan Tella, Kyle Walker-Peters, Lyanco, Armel Bella-Kotchap Kamaldeen Sulemana and Paul Onuachu among others, so it could be a very busy final week of the window on the south coast.

SUNDERLAND

Dominic Shaw, The Northern Echo

Sunderland made a quick start to the summer with four signings, with one of those arrivals, Jobe Bellingham, having made an impressive start to life at the Stadium of Light.

The Black Cats have signed two strikers - Luis Semedo and Eliezer Mayenda - but more are required, particularly if, as expected, Ross Stewart joins Southampton. That would leave Sunderland ideally needing two strikers ahead of the Friday night deadline.

Mowbray has also made it clear he'd like to sign a midfielder.

Exits are possible, with the future of Alex Pritchard, Danny Batth and Lynden Gooch uncertain as things stand.

The Northern Echo:

STOKE CITY

Pete Smith, Stoke Sentinel

It's been a radical summer at Stoke, having emerged from the worst constraints of Financial Fair Play with a whittled-down squad ripe for a major rebuild. 

Alex Neil spent the early part of pre-season putting together a Championship-hardened spine and over a frantic month had signed a group that should be pretty competitive - and play the aggressive, front-foot style he wants.

Now they can have a bit of fun. They're well placed in terms of budget and want to find players who can really be differentials in such a tight division, as well as having one eye on the long-term with young talent. Having only signed one player without experience in Britain in the last five years, the net is suddenly being spread across the world. There's no position they're not looking at and they'll keep maneuvering right up to the deadline. 

There have been busy summers in the recent past but there could be 15 or more new faces this time. The hope is that the platform is being laid for future windows to be nothing like as hectic.

In terms of outgoings, Lewis Baker, who is recovering from knee surgery, and Josh Tymon aren't as high up the pecking order as they would want while youngsters including D'Margio Wright-Phillips will be available on loan.

SWANSEA CITY

A replacement for left-back Ryan Manning is a top priority, with manager Michael Duff admitting Stoke City's Josh Tymon - reportedly valued at around £1.5m - just one of several players he's looking at for that position.

The Swans are also keen on a striker following the recent departure of Joel Piroe. The club are understood to have held initial talks over a move for Aston Villa's Keinan Davis, but it's not quite clear where that move now stands.

Goalkeeper Steven Benda is close to making a £1m move to Fulham, though it looks like Carl Rushworth will be given the opportunity to fill his boots.

Duff said: "Without labouring the point, we know we need a few people in and hopefully we'll get that. If we don't, we don't. It is what it is."

WATFORD

Andrew French, Watford Observer

First game very good, second game good, third game not good. Blowing QPR away on the opening day got a lot of people excited: four goals in the first half is a rarity. It was a revelation for Watford fans to see players putting in a shift, showing they cared and generally busting a gut. 

New head coach Valerien Ismael’s approach and firmness on expecting the right attitude has been obvious, but the 0-0 draw with Plymouth was less impressive and the 1-0 defeat at Stoke harked back to much of the mundane on-the-road misery of the last two seasons. 

The fans have been clamouring for more signings given the Hornets sold £50m worth of players. Young Danish striker Mileta Rajovic was signed for around £1m last week but Ismael has said he’d like to reinforce in other areas too.

The last few days of the window will be key as any goodwill Ismael has banked so far will be easily undone if the club don’t back him in the transfer market.

WEST BROM

Joseph Chapman, Birmingham Live

West Brom's financial problems are such that the final week of the window will be a 'one out, one in' policy.

They've bid farewell to eight senior players since the end of last season and have brought two in, in the form of Brighton winger Jeremy Sarmiento on loan and striker Josh Maja on a free transfer, but Carlos Corberan is eager to add at least a couple more. 

Loaning Taylor Gardner-Hickman to Bristol City last week has given them wriggle room in their recruitment hunt, but more players could still leave. 

The likes of Grady Diangana, Alex Mowatt and Nathaniel Chalobah have bit-part roles in the first-team set-up and could be allowed to leave if offers were to land. 

Albion do need another attacking reinforcement and a versatile full-back. Any new signings are likely to be Premier League loans.
