Manchester United forward Alexis Sanchez says he lost his confidence under former manager Jose Mourinho.

Sanchez joined United in January last year from Arsenal but the 30-year-old fell out of favour prior to the Portuguese’s departure in December the same year. He has only scored five goals in all competitions since arriving at the club.

In an interview with BBC, the Chile international described Mourinho as one of the best coaches in the world but feels the gaffer created an unhealthy atmosphere at Old Trafford.

“Mourinho is one of the best coaches in the world, in the way that he coaches, how he studies videos, the way he goes about things,” Sanchez said.

“But within the group, there was that feeling that you were in the team, then out. Sometimes I didn’t play, then I did, then I didn’t and as a player, you lose confidence.

“Then an atmosphere was created that wasn’t healthy.”

Sanchez, however, has continued to struggle under interim boss Ole Gunnar Solskjaer with the current boss even claiming that the 30-year-old needs to find himself and hit top form.
