Indeed, Hart only has to see what happened to Shay Given to keep him motivated.
He said: "Obviously I was planning my options otherwise because I have total respect for Shay Given.
"He is a great goalkeeper and I am truly honoured to play instead of him, because he is one of my heroes in the Premier League, and training day-in day-out with him. It is a shame there is only one spot for a goalkeeper.
"Mancini is a demanding manager and that's what you want. Picking me in the first place was saying 'You'd better go out and show why I've put faith in you' and I've got a lot of respect for him for doing that.
I'm really thankful for everyone who's shown faith in me. My whole aim is to repay them. I have not had any run-ins with the City manager. It's not my nature."
