Manchester United legend Roy Keane has slammed the season form of Paul Pogba.

The club record signing has been dropped by Jose Mourinho for big games in recent weeks despite his £90m price tag.

"Pogba, we've spoken about Pogba a number of time. He's not the only problem," Keane admitted on ITV's Champions League coverage.

"But if he can't get in the starting XI, you're in trouble.

"He comes on, you expect good players to affect the game, he came on last night and done nothing.

"We saw with the goal, his reaction to it was like a school boy. 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."
