"I think we have a good chance to progress despite the defeat. In the past, many great teams have come to Old Trafford after a first-leg victory and United still managed to get through.
"Roma are among the best teams we have faced this season. There was a great atmosphere here tonight and my younger players were a bit excited. It was a difficult game, especially after we went down to ten men. We tried to stop them by keeping our central midfielders very close to each other.
"Rooney's still young and can improve but tonight he scored a great goal and also defended well when needed. It's a pity to have lost Scholes for the return and I just hope we will not lose other players through injury next week."
