Rooney bagged two goals either side of half-time before Juan Mata added two more to put gloss on a fine afternoon’s work for Giggs’ men.
“We knew it was going to be a tough game because Norwich are fighting for their survival,” said Rooney. “Going in one up at half-time was good for us. We knew we would have to score again and once we did we broke them down more easily. It was a comfortable win in the end.
“We’ve had a tough week. We understand there has been a lot of negativity towards us as a team. We were hurt by that and we want to put it right. We know we are better than we’ve shown [this season]. We showed that we are a good team and it’s important for us now to end the season well. That’s what we intend to do."
A club legend taking over as manager in United’s time of need instilled a feel-good factor around Old Trafford, although Rooney said it felt “a bit strange” playing for someone he has called a team-mate for the last decade. “I’ve played with him for the last ten years, but Giggsy has come in and we know he’s a really experienced player and he’s also been a part of the coaching staff for the last season.
