Manchester United boss Sir Alex Ferguson admits they were fortunate to escape Norwich City with the three points.

After falling behind to a close-range header from Paul Scholes on seven minutes, the Canaries rallied and forced David de Gea into a string of fine saves.

The United keeper was finally beaten seven minutes from time by Norwich skipper Grant Holt.

However, that just served to spark the Red Devils into life as Ashley Young's goalbound effort was blocked and Danny Welbeck somehow missed a free header from two yards before Giggs ensured a fairytale finish when he stabbed home to keep United on the tails of Barclays Premier League leaders Manchester City.

"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."
