Paul Scholes had given the Premier League champions the lead inside seven minutes, but a Grant Holt effort with six minutes remaining looked to have salvaged a point for the Canaries; however Giggs had other ideas and scored in the first minute of stoppage time.
Sir Alex Ferguson was not especially happy with his team’s efforts at Carrow Road, but heralded the achievements of his veteran midfielder.
“It could prove to be very special, but for Ryan to score the winning goal with the last kick of the ball on his 900th game, well, he probably deserves that for the career he’s had,” the Scottish coach told Sky Sports.
“But I have to say we were lucky today in the sense that although we made a host of chances, Danny Welbeck could have scored four. I thought Norwich were the better team.
“In that first half, they put 12 crosses into the box and if it wasn’t for (Rio) Ferdinand, (Jonny) Evans and David de Gea, we wouldn’t have survived it,” he admitted.
Giggs meanwhile was delighted with grabbing the winner, which he hopes will help The Red Devils in their title ambitions.
“Yeah, it was obviously special and Norwich made it a tough game for us and they played really well. To score late on is always nice and to get the winner is a bonus,” he concluded.
