He told BBC Radio Five's Sportsweek programme: "I'm not established yet with England but I really enjoy playing and I know I have a lot to learn. It is amazing what Sven has done. He's had money to spend and has bought the right players.
"Stuart Pearce was a manager who liked to say 'come on, let's get up for this' but Sven is more relaxed, a nice chilled-out sort of guy who gives belief to his players.
"It is nice when a manager talks to you and lets you know what he is thinking. You can also let him know what you are thinking too.
"I'm very happy at Manchester City and, hopefully, I'll have something signed soon."
