Manchester United bowed out of the Champions League to Barcelona 4-0 on aggregate on Tuesday night, leaving only a top-four finish in the Premier League as the club's remaining aim for the season.
Ole Gunnar Solskjaer's side are currently sixth, two points behind fourth-placed Arsenal.
While elimination at the hands Barcelona is by no means an embarrassment, too many players have reverted to their previously underwhelming personas after a mid-season mini-revival under Ole Gunnar Solskjaer. Too many were second best in all areas across 180 minutes to Lionel Messi and co.

The Norwegian, who was named United's permanent manager in March after a hugely impressive spell as caretaker, will do well to look back on the club's signings since Alex Ferguson stepped down as manager in 2013 to see the type of player United should avoid signing.
