Nemanja Vidic injury is the reason for Champions League omission.
Nemanja Vidic was surprisingly left out of Manchester United's starting line-up against Olympiakos, but he has not been dropped according to manager David Moyes.
Vidic gave away a penalty at the weekend against Liverpool and did not make a single successful tackle; but it's injury rather than that poor display which explains his omission from the crucial Champions League second leg.
Manager David Moyes explained to SkySports:
"Vida's got a groin strain so we have had to make a change at the back."
The Serbian was pictured in training 24 hours earlier and appeared to show no signs of a lack of fitness, as seen above, so the news must have meant been a particularly late re-shuffle for the manager's plans.
Jonny Evans and Chris Smalling also miss out through injury with Vidic not even making the bench.
Rio Ferdinand and Phil Jones start the game, but the Red Devils do not have a named centre-back among their substitutes, with Michael Carrick most likely to fill in if required.
