Alexis Sanchez struggled against Sevilla on Tuesday night

Charlie Nicholas says the arrival of Alexis Sanchez has spoiled Manchester United's system and he must be dropped following their Champions League exit.

Jose Mourinho's side lost 2-1 at home to Sevilla on Tuesday evening to exit the Champions League at the last-16 stage, meaning the FA Cup is now their only realistic chance of a trophy this season.

Sanchez joined from Arsenal in January, but gave the ball away on 20 occasions in the game, and Soccer Special pundit Nicholas believes his arrival has had a negative impact on Mourinho's formation.
