Uniteds record signing has found his form under severe scrutiny in recent weeks and has been in and out of Jose Mourinho’s starting XI.

Pogba came off the bench with the score at 0-0, but looked poor all night which ended in an embarrassing 2-1 defeat.

Keane believes Pogba’s form is emblematic of the problems faced by Mourinho and his squad.

«Pogba, we’ve spoken about Pogba a number of times. He’s not the only problem, but if he can’t get in the starting XI, you’re in trouble, Keane told ITV.

«He comes on, you expect good players to affect the game, he came on and did nothing.

«We saw with the goal, his reaction to it was like a schoolboy. He doesn’t smell danger. The reason you’re in a team is if one of your mates makes a mistake, you cover for him.

«You make up for him, nobody is helping each other. They’re playing as individuals.
