Manchester United boss Sir Alex Ferguson will wait until today to make a decision over the fitness of Wayne Rooney and Nemanja Vidic ahead of tonight's clash with Barcelona.

"Obviously for such an important game, we've got to give them every chance," said Sir Alex, at Monday's pre-match press conference.

"Nemanja didn't train yesterday or today, neither did Wayne. It's a difficult one. We think both could make it but I can't be dead certain."
