He revealed his Spanish pal David Silva helped to make up his mind to leave his boyhood club and try his luck in England.
He said: "We get on pretty well and a long time ago, when he found out I was coming here, he was very happy. I know he enjoys the city and the club.
"Now I have the confidence I can play here and I'm very happy to be at such a big club.
"Everything about English football is exciting. It's fast, it's end-to-end. It was my idea to come to the Premier League and enjoy this kind of game."
