Manchester City goalkeeper Joe Hart feels a cleansheet in victory over Chelsea has silenced his critics.

The City keeper was dropped by boss Roberto Mancini after his howler led to a goal in the 3-1 Premier League defeat at ­Southampton.

He was replaced by Costel Pantilimon for the 4-0 FA Cup home win over Leeds.

"We all underperformed in the Southampton game, but we have had to put it behind us,'' said Hart.

"You just move on from that and look forward."
