Manchester United boss David Moyes feels they can spring a Champions League surprise this season.
Moyes' men will attempt to rescue their sorry season when they travel to Olympiakos on Tuesday night.
He said: "It isn't always the best teams that get to the final in Europe. Liverpool in 2005 gives us hope, but in any cup competition you always have a chance.
"I knew it was going to be a hard competition before it started. Bayern Munich, Barcelona, Real Madrid and PSG are all top clubs."
