Chelsea midfielder Frank Lampard says there's no doubting the genius of Manchester United star Wayne Rooney.

Lampard said Rooney had made an instant impression when he was first selected to play for England.

"He looks like he has this bulldog way about him, a little powerhouse, and then the first day he trained you could see he had this touch and awareness that was …like a genius touch," Lampard said.

"I'd only seen three players in my career like that - Paolo Di Canio, Gianfranco Zola and Paul Gascoigne when I was a kid training with England - that had this genius kind of thing about them, and Wayne had that instantly as a 17-year-old."
