According to French outlet, L’Equipe, Pogba’s relationship with Mourinho at the moment is “difficult”.
The midfielder was substituted off during United’s 1-0 defeat at Newcastle last weekend.
It is the second time in three games, Pogba has been taken off by Mourinho.
After the clash, Mourinho was asked if there was an injury.
“No, no problem.
“I wanted a better way to come out in the first phase against a team that was defending in a very compact block.
“I was trying that with the simplicity of Michael Carrick because he tries to make everything simple and bring Alexis in an area close to Lukaku where he can be like a second striker.
“I was unlucky because they scored a goal in the seconds after, and then I’m going to face a different Newcastle where in that moment the only thing they think is defend,” Mourinho said.
