Santa Cruz has been on loan at Malaga and the 31-year-old insists that there will be no hard feelings between himself and City.
Roque Santa Cruz: "At City I had an excellent relationship with each of the coaches that I had - Mark Hughes first and Roberto Mancini later - as well as with the club.
"Mancini was honest with me and I don't blame anyone. They made big investments and I wasn't able to play much, but there is no blame.
"During my season at Manchester City I was not 100 per cent fit, like I am now. But I am not going to go back there.
"In June, I will not be a player of Manchester City anymore. The contract has expired."
