"Ten has always been my favourite number," he told Inside United magazine. "It's definitely been an important number down the years. It's probably more of a traditional number in South America for the best players to wear No 10.

Rooney singles out Pele and Maradona as two of his greatest idols.
He said of Pele: "I've watched lots of videos of him and you can see what a brilliant footballer he was. He had two great feet, was strong in the air and also a very good athlete. He's rightly up there as one of the best players of all time."
Of Maradona, he says: "He's definitely the best player there's ever been in my eyes. He had pace, great skill and an unbelievable desire to win."
