David Silva says his success at Manchester City is due to manager Roberto Mancini.

The former Valencia winger says Mancini has brought out the best in him.

"It is so difficult to change club and country and adapt to a different style of football, and it is down to Roberto Mancini that I have done so well," he said.

"In my second season in England I feel more settled than ever, on and off the field, and that is down to the manager and his staff. It is because I am happy off the field that I am playing so well on it."
