Liverpool legend Mark Lawrenson says Manchester City must sell Mario Balotelli next month.

Lawro wrote in the Mirror: "If I were Roberto Mancini this morning I would call Mario Balotelli into my office.

"I would also get hold of his agent and say: 'Right Mario, sort out your transfer, you can leave tomorrow.'

"Honestly. I would sell him on the first of January if I could. Because he was an absolute disgrace yesterday.

"And I cannot believe Roberto Mancini preferred him to play alongside Sergio Aguero instead of Carlos Tevez in the Manchester derby.

"When he DID put Tevez on for Balotelli, a few minutes into the second half, the difference was immediate."
