Alexis Sanchez has revealed he asked his agent if he could leave Manchester United and return to Arsenal after only one training session.

The 31-year-old took to Instagram on Thursday night to tell his side of the story about his failed move to Old Trafford in 2018, which saw Henrikh Mkhitaryan move in the opposite direction and join Arsenal.
