Former Arsenal manager Arsene Wenger believes Manchester United midfielder Paul Pogba will never reach his best when he's lacking fitness.
Wenger thinks until Pogba is fully fit he will never be able to recapture his best form.
"First of all, I think Paul Pogba since the start of the season has never been completely fit injury wise," Wenger told beIN Sports.
"He doesn't look completely confident physically and he's the type of player who has a huge physical power. He needs to be perfectly fit physically."
Pogba admitted he was interested in a "new challenge" at the end of last season, and Wenger also thinks he is unable to perform at his best when he is thinking about moving to another club.
He added: "After that, when a player wants to leave and you stop him from leaving, you know you go through a process of rebuilding the relationship that the first thing that suffers is the performances.
"I personally think he behaves as well like he knows that Man United at the moment is not the team to compete for the championship. And, plus the fact that he was stopped from going away, it looks like the two together a bit tarnish his performances."
