Manchester United go into Wednesday night's game against Arsenal knowing that a defeat will see them cast aside in the chase for the top four places in the Premier League.
But what side might line up on the pitch for the home team at Old Trafford is anybody's guess.

In fact, United have not started a single Premier League game with the same team that started the previous match across all 14 of their games so far.
