Hart was dropped and his City future threatened halfway through the campaign.
The England goalkeeper said: "It has been a good season, a tough season, but one I have enjoyed.
"It was difficult for me personally but the beauty of this team is that we have got people who can fill in at any time.
"Costel (Pantilimon) was absolutely fantastic when he played, I got taken out of the team.
"He's been brilliant, a pleasure to work with, the same as Richard Wright, and Xabi (Mancisidor) has come in and been a great coach. As a goalkeeping unit we are really blessed at this club and I am proud to be part of it."
