Manchester United's season hangs in the balance tonight as they host newly crowned Greece champions Olympiakos at Old Trafford.

Their 3-0 loss at home to Liverpool last week all but ended their chances of a top four finish this season, while a 2-0 defeat in the first leg of this last 16 tie means failure to progress tonight could be the final nail in the coffin for their hopes of Champions League football next season.

David Moyes insists his job is safe, despite growing speculation that the Old Trafford board have already discussed potential replacements. He will need to win tonight, though, to back up any claims that he is still the right man to continue Sir Alex Ferguson's trophy-filled 25 years as boss before him.

Here are tonight's confirmed starting line-ups for both sides...
