Alexis Sánchez is reportedly undergoing extra training sessions in order to revive his form at Manchester United.

The 29-year-old completed a switch to Old Trafford from Arsenal in January but has since struggled to acclimatise.

However, the Daily Star claims that Sánchez has cut an isolated figure because he is often last off the training ground.

The outlet quotes a source as saying: “He regularly does an extra 30 minutes working on free kicks and shooting after the main session has finished up.

“By the time he has showered and changed, the majority of his teammates have finished eating and gone.”

Sánchez told Chilean media last week that the move has been difficult ‘both physically and psychologically’ but expects to settle in Manchester soon.
