The 25-year-old England international was beaten by former club-mate Adam Johnson's long-range shot at the Stadium of Light on Boxing Day to condemn City to a third successive 1-0 Barclays Premier League defeat at Sunderland.
Joe Hart: "The only way we can change it is by winning here next year - but for now, we only have Norwich on our minds.
"Simon Mignolet has had a magnificent game. He's a brilliant goalkeeper, I have watched him closely in other games.
"Sunderland defended for their lives and it just wouldn't go in for us.
"First and foremost, someone stamped on Zaba - it was a blatantly obvious foul - but what can you do?
"I was in my position for the shot, and that's where you will see me again on Saturday.
"But he struck it well with just enough wobble to beat me."
