England boss Fabio Capello is convinced Manchester United ace Wayne Rooney can become an even better player.

"Wayne is young and he can improve," said Capello.

"I accept it is more a case of going upwards a little bit from 90% rather than 70% but he can improve three or four percent and that is very important.

"I have been very happy with Wayne. This season he has done very well. He is in a fantastic moment right now and I hope he is the same next year."
