Stuart Broad has promised he does not intend to "reinvent the wheel" when he starts life as England's new Twenty20 captain in Bristol today.

Broad is the second of three captains in as many matches against Sri Lanka, taking over the reins from Test skipper Andrew Strauss before passing them on to new ODI leader Alastair Cook on Tuesday.

It will be his first taste of captaincy as a professional cricketer, having only ever skippered at schoolboy level, and he does not intend to revolutionise a side who became World Twenty20 champions last year under predecessor Paul Collingwood.

"I'm going to be very honoured to lead England and I think it's a very exciting squad," said Broad, who is fit to play after overcoming a bruised heel and an awkward fall in training yesterday.

"I'm going to be diving into the experience and I'm really looking forward to it.

"I don't think we have to change a huge amount in this Twenty20 side because we've had some success. We are World Twenty20 champions and went on an unbeaten run that was pretty much world-record stuff, so we have some very good principles we perform to.

"I'm obviously going to have my own ideas, but we certainly aren't trying to reinvent the wheel."

Broad is unflustered about his lack of captaincy experience, a result of his elevation to senior international cricket at the age of just 20.

That has denied him the chance to lead age group sides or at county level, but he feels his experiences with recent England captains have proved even more helpful to his development.

"My captaincy experience has been pretty limited in the professional game, but part and parcel of getting picked for England quite young is that you never have a chance to captain a side at a younger age," he said.

"But I always have a mindset when I walk on to the pitch that I have to think like a captain with your field placements and what balls to deliver.

"I've been very fortunate to play under the likes of Michael Vaughan, Andrew Strauss and Paul Collingwood, some brilliant captains and I've learnt a lot. I feel 100 per cent ready to lead the side.

"I don't get fazed by that, I feel I've learnt a huge amount so I don't think the lack of experience will be a problem."

Broad, 25 yesterday, admitted Collingwood had been devastated to find out he was a casualty of England's forward planning, but said the all-rounder had already been in contact to offer his support.

"I've spoken to Colly, when he's not been on the golf course, anyway," Broad added.

"He was heartbroken to lose the England captaincy and I think everyone understands that. But he has been very supportive. He was the first guy on the phone to congratulate me and that's the sort of character he is."

Broad will come up against another rookie captain in Sri Lanka's Thilina Kandamby in Bristol. He will take charge in place of Tillakaratne Dilshan, who has yet to recover from a fractured thumb.

Kandamby faces the unenviable task of beginning his reign with a trio of vastly experienced former captains - Mahela Jayawardene, Kumar Sangakkara and Sanath Jayasuriya - in his side. But the 29-year-old said: "It is good that I am starting my career captaining at this level with that experience behind me."
