Some fans believe the Frenchman isn’t playing to the best of his ability consistently enough due to Jose Mourinho.
The pair are also not exactly on the best of terms with their relationship said to be practically non-existent.
Merson though has defended Mourinho stating that a player has to, at a certain point, start to take responsibility for their own form.
Pogba was recently hauled off in the second half of the clash against West Ham which ended in a 3-1 loss.
According to the Sport Review, Paul said to the Daily Star: “I don’t think he’s improved at all since he joined United. Even Michael Carrick used to dominate games from midfield more often than he does.
“I would like to think it’s not immaturity. He’s not young any more (25) and has played a lot of big matches.
“But what is his position? Does he have the discipline to be a central midfielder? Can he do that consistently? Can you trust him with a free role?
“It’s not easy at United because they’re not playing free-flowing, attacking football. But he would have known that before he signed.
“You can’t keep saying it’s all the manager’s fault they’re not getting the best out of him.
“Sometimes you have to look at the player. When a manager digs him out, how does he respond?
“Too many players these days are paid so much money they sulk – or try to undermine the manager and get him sacked.”
Jose’s main issue with Pogba has been his inability to maintain a standard of performance since arriving at United.
The Frenchman cut a frustrated figure last weekend and has not been consistent so far this season either.
In his third campaign at the club Paul should be hitting his stride, particularly after winning the World Cup.
Perhaps the ongoing power struggle within the club hasn’t helped matters but there’s no doubting fans want to see more from the former Juventus man than he’s currently offering.
