Now 37 and already the most decorated player in the history of the English game, Giggs could be forgiven for getting fed up with seeing United being forced to fight back from seemingly impossible positions.

But the midfielder laughed off such suggestions after adding yet another entry to the pantheon of turnarounds that have been a hallmark of his legendary 20-year career.

"It's what it's all about - it's a challenge," said Giggs after United scored four times in 19 minutes to turn a 2-0 Barclays Premier League deficit at West Ham into a 4-2 victory.

"You enjoy it more than ever."

Giggs must have lost count of the number of comebacks in which he has featured but yesterday's will have been one of the more memorable for the veteran Welshman.

Manager Sir Alex Ferguson's decision to go for broke at Upton Park saw Giggs play the entire second half at left-back.

That was one experience the player was not keen to repeat, saying: "I don't want to play there again."

Houdini acts have become the norm at Old Trafford during Ferguson's reign and Giggs has played a crucial part in helping develop that culture.

But he revealed it is still the manager who takes the lead in rallying the troops at half-time matches such as yesterday's.

"The experienced players obviously have been there and done it," Giggs said.

"But I think the manager is obviously the one who believed in us."

And despite the inexplicable manner in which United conceded two penalties to fall 2-0 behind yesterday, the hairdryer was kept in its locker.

"Calmness," was Giggs' assessment of Ferguson's demeanour.

"To go down with two penalties is always disappointing.

"It was just a matter of concentration once you're in the last third."

Yesterday looks set to prove a pivotal day in the title race.

Defeat for United would have opened the door for Arsenal and Chelsea to close to within striking distance.

But United's win and draws for their closest rivals left Ferguson's men a clear run at the championship.

Giggs believes yesterday's result sent a message to Arsenal and Chelsea but insisted getting over the line will not be as easy as some are now predicting.

"Teams are either fighting relegation, or going for Europe, or going for Champions League," said Giggs, who is closing in on a record-breaking 12th league title.

"There's always something at stake.

"So every game is a cup final now - seven games to go."

There is also the small matter of a Champions League quarter-final against Chelsea, starting with Wednesday night's first leg at Stamford Bridge.

Giggs said: "It's such a tough place to go, Stamford Bridge, and Chelsea are playing well as well.

"You want to go into that game in good form, both personally and as a team."
