Ryan Giggs claimed the reception Old Trafford gave him as Manchester United manager made him feel "10 feet tall", then admitted he was unable to sleep the night before the 4-0 win against Norwich through worrying about his team selection. "Leaving out players was the hardest part," United's interim manager said. "I'd never had to do that before, but I picked a team I thought could win the game."

One of the players Giggs left out was Juan Mata, United's record signing at £37m, though he came on for the last half-hour and scored twice so everyone was happy. "I think as a manager a win comes as more of a relief," Giggs said. "Juan was disappointed to be left out, and I expected that, but he was professional about it and when he came on he showed his class. He put on a half-hour masterclass."

Wayne Rooney, who also scored twice, said Giggs has what it takes to be in permanent charge. "He's built to be a manager," the striker said. "You can see that from the way he handles himself. Obviously that decision is down to the board, but Giggsy has all the credentials to be the next boss."

Giggs himself is not looking beyond the immediate future. "The focus is on Sunderland now," he said. "I can't look any further ahead than that."

According to Rooney, the United players should accept some of the blame for the disappointing results under David Moyes. "Of course we should, we underperformed," the club's top scorer said.

"We have to share a lot of the responsibility but it is also important for us to move on. It was tough at the start against Norwich but once we scored we were able to break them down more easily."
