City boss Roberto Mancini was quick to point out that the season was only at the halfway stage as he assessed the implications of an unexpected defeat, and Hart remained equally bullish.
He told the club's official website: "We have had leads, United have had the lead - it's to-ing and fro-ing at the moment.
"We are a team of winners. It's hard and it hurts, but we have got to move on. It is hard to lead and it is hard to chase too.
"We have clawed points back before, we proved it at the end of last year. We have just got to believe."
