Paul Lambert insisted Norwich City had no more to give after Premier League champions Manchester United grabbed a stoppage time winner in today's 2-1 victory at Carrow Road.

Ryan Giggs marked his 900th game for the Red Devils with a close range finish after Grant Holt had cancelled out Paul Scholes' early goal. Holt's 10th of the campaign merely sparked United into a ferocious late onslaught which paid dividends when Ashley Young picked out the legendary Welshman.

'That was a huge performance by us. We gave everything,' said Lambert. 'We were running on empty, but I couldn't fault our lads. Manchester United come at you from all angles, but I couldn't ask for any more.

'The first goal was a poor goal to lose but the pleasing thing was, when you lose that goal early, you don't capitulate, and we never did that. We hung in and the United goalkeeper probably saved his best game for against us - some of his saves were magnificent.'

Sir Alex Ferguson conceded the visitors had survived an almighty scare.

'I have to say we were lucky today, in the sense Norwich had more promise about them. I thought we were lethargic, too casual on the ball. Then when we lost the goal, we played brilliantly,' Ferguson said on MUTV. 'That tells you something about the temperament, they do not get nervous and started to up their game, so that augers well for us.

'I think the players were probably a bit embarrassed with the chances they missed, they know they should have done better during the game, and that is irrespective of Norwich being the better team.

'They just kept crossing that ball into the box. Without Rio Ferdinand, Jonny Evans and (David) De Gea, we would have been down. They were brilliant the three of them.

'Norwich deserved a point today and it was a great goal they scored, but at that moment you saw us as Manchester United. I am sure this result will have an impact. Everyone knows we never give in, no matter who plays us, they know they will have to play right to the death.'

Man-of-the-moment Giggs admitted it was a 'real honour' to mark his landmark game with the winner.

'It doesn't get any better,' the Welshman told BBC Sport. 'Norwich put up a great fight but we didn't really play very well. We started the game really well, scored and took our foot off the pedal and Norwich caused us a lot of problems. But I think if you look at the last 10 minutes, we probably just deserved it.

'We have been in good form recently, gone to some tough places over last three or four weeks and got some great performances. Today was more about the result than the performance.'
