Manchester United defender John O'Shea says they face great competition in this season's Champions League.
He told manutd.com: "You'd have to say so. The age of their team and their vast experience make them very strong, but we don't feel like we have anything to fear. We know the result in Rome could easily have gone the other way and it could have been our night.
"Real Madrid have obviously spent a lot of money and spent well! Internazionale look a better team and I'm sure Chelsea will be there or thereabouts, while Liverpool have great experience in the competition as well.
"So there are a few teams in with a good chance."
