MF Bastian Schweinsteiger
Schweinsteiger has been in big Champions League matches before, but this will probably be his biggest yet as a member of Man United.
MF Morgan Schneiderlin
The former Southampton star has adapted to the Champions League very nicely and should once again dominate ball control and time of possession.
MF Juan Mata
Just about the only consistent scoring threat left for Louis van Gaal, Mata will be vital in this match.
MF Ashley Young
Ander Herrera is hurt so Young will need to move back to midfield at least until the team gets healthy again.
