#2. Alexis Sanchez
No one has been as disappointing at Old Trafford this season as former Barcelona winger, Alexis Sanchez. The Chilean joined Manchester United from Arsenal during the previous campaign in a swap deal that saw Henrik Mkhitaryan going the other way.
However, he has failed to contribute any reasonable impact at the club ever since switched to Manchester - bagging an embarrassing 3 goals and 6 assists for the Red Devils and prompting some sections of the Old Trafford faithful to brand him their worst signing of the decade.
Considering his huge wage structure and the level of expectations before him, it is now or never for Alexis Sanchez to step up and revive his reputation at the club. He has immense technical qualities and vast experience which he needs to utilize to the benefit of the team.
