Fabio Capello is adamant there is more to come from Wayne Rooney.

England's star striker has enjoyed a superb season on the international stage and grabbed another two goals in the 6-0 win against Andorra on Wednesday night to shoot to the top of the World Cup goalscoring charts. In addition, Rooney also matched Gary Lineker's record of 10 goals in an England season.

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

The 23-year-old's outstanding form has given rise to an optimistic groundswell of opinion over England's chances in South Africa next year should they collect the single win from three remaining games required to take them to the World Cup Finals.

With Cristiano Ronaldo headed for Real Madrid, Sir Alex Ferguson is now as reliant on Rooney as Capello.

But the Italian is confident the former Everton star can deliver.

Capello added: "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."
