Khan in a class of his own

Amir Khan, Britain's teenage boxing sensation, is "unbeatable" according to the man who tried to plot his downfall last night.

Khan, our only boxer at the Olympics, reached Friday's semi-final after stopping South Korea's Jong Sub Baik in 97 seconds. It was a superb display from the 17-yearold and Baik's coach, In-Suk Oh, said: "This boy is unbeatable. Khan will be considered the memory of the Games."

Khan, who now fights Kazakhstan's Serik Yeleuov for a place in the final, said: "It is a great achievement to win a bronze medal at my age. You can't really expect any more from a 17-year-old.

"But now I've got that bronze the pressure is off and I'm sure I can go on and hopefully win gold."
