It led to manager David Moyes labelling him a "freak" after the game, while his team-mates were left shaking their heads in continued admiration.
"What's left to say about him?" said Michael Carrick. "It's incredible to come into a game like that, having not played a lot of football recently, and get through it physically – it shows how he looks after himself. His ball for Wayne [Rooney] for the second goal was typical of him. He can still do it and it's a pleasure to play with him."
Phil Jones added: "He's terrific. He drives the team forward and the ball for the penalty was exquisite. You can't teach that. He's a great lad as well."
And Patrice Evra said: "The legend, Ryan Giggs... I don't know how many words you can say about his class. I have so much respect for him. He's such an example to me. When I joined this club, a lot of people were talking about Cristiano Ronaldo and Wayne Rooney but Ryan was always my favourite, along with Scholesy and Gary Neville."
