Nigel de Jong insists he's happy at Manchester City.

The midfielder has rejected claims he's unhappy with his contract.

"There is no concern about my contract," he said. "I have spoken my mind, it is up to the club to decide what they want to do now.

"I have been here for three years and I am happy.

"I am here to win prizes. We won the FA Cup last season, now we are doing well in the Premier League. For me there is no reason to move on."
