Napoli coach Maurizio Sarri has challenged Gonzalo Higuain to fulfil his potential.
Sarri rates Higuain the best striker in the world and feels there's more to come from him.
"If he doesn't win the Ballon d'Or in future then it'll be all his fault! He'd be a right ****head.
"He is the best centre-forward in the world," said the coach.
