Former Liverpool captain Paul Ince says they must flog Mario Balotelli in January.
Balotelli, who sealed a £16million move to Anfield in August, has failed to score a Premier League goal since joining.
Ince told talkSPORT: "I just watched him play [against Manchester United] and he plays for himself. You can see the frustration in the other players. There was a time when he could have put another player in but he didn't.
"It seems like people are frightened to say something to him in case he goes the other way. They keep saying what a great, talented player he is but I'm yet to see it.
"I think the quicker Brendan Rodgers sees it and can get rid of him the better, to be honest, and the better it will be for everyone because there is a lack of spirit in that Liverpool side."
