Liverpool legend Jamie Carragher has slammed Paul Pogba's derby performance.

World-record signing Pogba came under heavy fire from fans after failing to sparkle in Manchester United's 2-1 weekend defeat against Manchester City.

Speaking on Monday Night Football, the Liverpool icon said: “I don't think it was so much Pep Guardiola getting it massively right, I think Jose Mourinho got it tactically wrong.

“What Mourinho wasn't helped by was the performance of his players – he made two changes at half-time – but specifically the performance of Paul Pogba.

“I think for a central midfield player in a game of that magnitude, it was one of the most ill-disciplined performances you'll see in the first 40 minutes.

“The only way to describe it was like a kid in the schoolyard, the best player in the schoolyard, he runs where he wants, does what he wants."
