Robinho has rebuilt his career at Milan this season.
He told ESPN Soccernet: "I don't think it is fair to say I was a disaster at City.
"It's important to remember that I scored 14 goals in my first season there and ended up as the club's top scorer. There were not too many more players in the Premier League who scored as often as me, so it was not all bad. For my first year in the Premier League, it went pretty well and I felt the City crowd were on my side.
"The trouble came in the second season. I had injury problems and the new coach [Roberto Mancini] went with other options in attack. I'm not going to blame Mancini for what happened because he had respect for me. He laid out what the situation was, but I did not feel as if I would be a regular part of his team and this was a problem.
"What made me want to leave was that [with] the World Cup in South Africa coming up, there was no way Dunga [the then Brazil manager] would have picked me if I was only playing occasionally for City. Being an impact player was no use to me and I had to go back to my old club Santos before finding a home here in Milan.
"Every experience in life has its good and not-so-good points. I have many warm memories of City. Certain goals, certain matches and, of course, the enthusiasm and passion of the fans. They are real people with the same sort of commitment to their club as a Brazilian supporter."
Robinho further explained why his compatriots fail to settle down in England quickly.
"England is a hard place for a Brazilian to perform," explained Robinho. "I'm an expressive and instinctive player, while the Premier League puts a lot of emphasis on systems and fitting into a certain mould.
"I wasn't helped either by the price on my head. City paid a lot of money and went to a lot of trouble bringing me in. The expectations on me were huge and in a way you become a target and it is also true that I had great difficulty adapting to life in England.
"It was a culture shock for me, the weather was very different, and I became unhappy. I live and play through my emotions and when they aren't right, I'm not right."
