Manchester United 1, Tottenham Hotspur 0.

Manchester United's latest Portuguese teen sensation rescued their Premier League title defence from the brink of oblivion at Old Trafford.

With United looking set for a point at best from their pulsating tussle with crisis club Tottenham, Nani repaid the first portion of his £17m transfer fee, belting a sensational winner past Paul Robinson from 30 yards.

It allowed Sir Alex Ferguson's men to register a first win of the season, and prevented them making their worst start since the year Ron Atkinson was sacked.

But it was tough luck on Spurs who put a week of off-field problems behind them to battle manfully throughout, producing a stirring display for their under-fire manager Martin Jol.

And they also had what they thought was a stonewall penalty claim turned down shortly before Nani's decisive strike.

How Jol must hate Old Trafford. Two years ago Jorge Mendes had a perfectly legitimate goal disallowed because none of the officials spotted his long-range shot had dropped over the line. Yesterday the Dutchman is probably nursing an equal sense of injustice, although this time it would be misplaced, as Wes Brown blocked Dimitar Berbatov's bullet strike with his chest rather than his arm as everyone of a Tottenham persuasion seemed to think.

Nevertheless, with Robbie Keane hitting the bar inside 20 seconds and Berbatov denied only by Rio Ferdinand's desperate goal-line clearance before the penalty claim, Jol could legitimately argue his side deserved much more than a third loss, which makes his stated aim of a Champions League place all the more harder to attain.

Not that Jol's troubles will concern Ferguson too much after United finally got their title defence up and running after a nightmare start.

The opening three games of their title defence has yielded the sum total of one goal and two points, and when kick off arrived, only Derby were below them table.

Robbie Keane had the perfect opportunity to inflict yet more damage inside the opening 20 seconds.

After Nani gifted Steed Malbranque possession deep inside his own half, he fed Berbatov, whose overall performance was exactly what United are lacking at present.

The Bulgarian's precise flick offered Keane his sight of goal. But, from 20 yards, the Spurs skipper could only clip the top of Edwin van der Sar's crossbar.

It was the nearest either side came to breaking the deadlock during an opening period.

On his home debut, Owen Hargreaves was off target with two long-range efforts, Paul Scholes flicked a shot wide and Michael Carrick was shaved the post with a 25-yard effort.

However, up front on his own, Carlos Tevez was ineffective. The need for support was clear for all to see. But, with Cristiano Ronaldo suspended, Wayne Rooney nursing a broken foot and both Louis Saha and Anderson still injured, the Argentina star foraged alone.

Spurs had another chance as Ricardo Rocha climbed above Rio Ferdinand but, from barely six yards, could only head Gareth Bale's free-kick wide.

There was not even an hour on the clock when Michael Carrick was taken off after a truly terrible performance against his former club.

It proved the spark for a 10-minute period in which Tottenham came agonisingly close to scoring, and they had what they felt was a certain penalty claim turned down.

When the Spurs side view the incident again on TV, they will see Berbatov's shot blasted against Wes Brown's chest after the striker had received a fortunate bounce of the ball in a challenge with Edwin van der Sar.

At the time though, the striker felt the spot-kick award was certain and he led a posse of around referee Howard Webb.

Just prior to that, Berbatov must have thought he had opened the scoring when he rose first after a tangle with Nemanja Vidic, then prodded a shot through Van der Sar's legs, only for Ferdinand to boot clear from virtually on his own line.

But on United's next attack Nani collected a loose ball 30 yards out, turned towards the visitors goal, then unleashed a magnificent shot which appeared to flick off Tevez before it flew in.
