Silva had a heartwarming moment in September when he received an amazing ovation from all four sides of the Bernabeu when he played against Real Madrid.
But he said: "I was very happy that night. To get that from Real Madrid supporters when you are playing for the opposition is not something that happens often.
"It's not an easy thing to achieve. I'm very grateful and proud that it happened.
"I'm very happy at City at the moment. I've no plans to move back to Spain, but you never know what might happen in the future. It's not something I'm thinking about at the moment."
