Former Manchester United goalkeeper Peter Schmeichel feels that Manchester City manager Roberto Mancini's criticism of his players could have cost them the Premier League title.

The Italian has been critical of his players in the media including captain Vincent Kompany and Samir Nasri.

Schmeichel told Sky Sports News: "Some players have been heavily criticised by the manager in public. Perhaps Mancini brings that from Italy.

"But that does not work here. I can understand that some of the players have been angry or disappointed with that type of treatment. Sometimes they will take that on to the pitch and maybe not play 100% for the manager.

"That never happens with [Manchester United manager] Sir Alex Ferguson. Never. Sir Alex is so consistent with his management. Manchester City have not had that."

City and United face off in the Manchester derby later today.
