Manchester United striker Wayne Rooney says teammate Cristiano Ronaldo deserved the World Player of the Year award last season ahead of winner Kaka of AC Milan.

"I am convinced that last season Cristiano Ronaldo deserved the Ballon d'Or," said Rooney.

"Kaka only won it because Milan won the Champions League.

"Ronaldo has incredible talent, and what he has done for United in these last two years is simply tremendous. Of course I want to be as good as him, I train every day for this."
