#2 Alexis Sanchez must be dropped
The Chilean made an encouraging start to his United career and has predominantly played in his favored role on the left, but Alexis Sanchez did little to justify his place on the left - let alone in the starting line-up against Sevilla.
Sanchez lost possession 42 times against Sevilla, and as he grew frustrated he dropped deeper. This caused more problems for United going forward as it stifled the midfield players.
In the meantime, his arrival at Manchester United has forced other players out of the team or out of position. Other players - Anthony Martial, Jesse Lingard, Juan Mata - who had been playing regularly and in fine form too, have been impacted negatively by his arrival.
Sanchez may have floundered against Sevilla, but it would be a major surprise if Mourinho dropped him for the FA Cup quarter-final against Brighton. Or even moved him out of his favored role on the left.
For sure the Chilean will improve - a rare end of season break (as Chile have not qualified for the FIFA World Cup) and a full pre-season with his new team will help him - but Mourinho has already proved he has no room for an 'untouchable' culture at United, with his treatment of Paul Pogba.
He needs to follow suit with Sanchez.
