Joe Hart has signed for Burnley for £3.5m on a two-year-deal.
The 31-year old former England number one has been with City for 12 years, although the last few have often been spent out on loan with West Ham and Torino.
"Joe Hart's contribution to Manchester City cannot be overstated," said Man City chairman Khaldoon Al Mubarak.
"His 12 years at the club have seen him produce some remarkable performances and heart-stopping saves that will live in the memory for a long time to come.
"He will rightly be regarded as a City legend in perpetuity."
