Manchester City striker Mario Balotelli has revealed the secret to his spotkick success.

The Italian has scored all eight of the penalties he has taken for City so far, and insisted that the key to his success is locked inside his head.

Balotelli said: "It's just like a game of the mind, between me and the goalkeeper.

"Me, I know how to control my mind. When the keeper moves before me, it means that in this game of the mind he has lost."
