The episode revolving around Alexis Sanchez will forever be a mystery to Manchester United fans. The Chilean international was expected to be a game-changer and match-winner for Manchester United but he failed to get going at all. Renowned football manager Jose Mourinho has now revealed the reason behind Alexis failure at Manchester United.

The former Manchester United manager, in a recent interview, stated that the main reason behind the failure of Alexis Sanchez at Manchester United was his unhappy state of mind at the club. He revealed that since he was feeling unhappy, it reflected poorly on his performance.

“Sanchez… I felt him not a happy man,” said Mourinho about the Chilean star as quoted by Daily Mail.

“And I think in every job you have when you are not happy it is not so easy to perform at every level. And maybe I am wrong. Maybe it was me who was not capable to get into him and to get the best out of him.

“As a manager sometimes you have the capacity to get the best out of the players and other times you are not successful in that approach.

“But the reality is that I always felt [of Sanchez], ‘a sad man’. So probably in Italy, he will recover this. I hope he can. I always wish well to every player,” he added.

Sanchez finally brought an end to his forgettable stint with Manchester United. He joined Inter Milan on a season-long loan for the season where he will play along with former Manchester United teammate Romelu Lukaku.
