Silva was strongly linked with a move to Real Madrid in the summer of 2010, but instead ended up joining City.
Reports in the Spanish media claimed Real Madrid did not want to sign Silva because of the winger’s ‘problematic’ lifestyle.
“If Real Madrid didn’t want to sign me I don’t know why these rumours came out, with accusations being thrown around,” said the 26-year-old.
“My conscience is clear and I have always been professional.
“That whole affair didn’t anger me but it puzzled me greatly. There was an interest but then Real tried to cover it up with that.
“But I am calm and very happy to have taken the decision I did.
“Neither Barcelona nor Real made any move. It was City who made a move for me and that is why I am here. I went where I was wanted.”
He added: “I was happy at Valencia but because of circumstances I had to leave.
“City put their faith in me more strongly than anyone else and I made the right decision.
“Mancini has given me total confidence and that’s very important for a player, while I am very happy that my team-mates are adapting to my game.
“I am very happy in England, I have two years left on my contract and I want to see it out.
“Right now I don’t want to return home, I’m enjoying myself and the people have treated me marvellously – and I hope to enjoy it much more.
“You enjoy football to the maximum here.”
