BOLTON'S boxing sensation Amir Khan is determined to turn his guaranteed bronze medal into gold.

The 17-year-old Heaton destroyer became the youngest ever British boxer to win an Olympic medal with victory over South Korea's Baik Jong-sub.

And he did it in sensational style as he stopped the man ranked fifth in the world after just 97 seconds of a one-sided contest which again highlighted Khan's incredible hand speed, power and technique.

It was a supreme lightweight division victory over the Asian champion which proved the Bolton student's incredible potential as he prepares for his semi-final on Friday and possible final on Sunday.

The youngster, who would be studying for his exams if he was not stunning the best amateur lightweights in the world, made the world sit up and take notice in his devastating first two fights.

He proved a serious gold medal hope as he put Baik on the canvas with a sweet right hand after just 60 seconds.

After another right-hand piledriver, the referee stopped the fight with 23 seconds of the first round left.

Britain's youngest ever Olympic boxing medal winner now has another piece of history in his sights.

He aims to become the youngest boxer to win an Olympic gold medal since Floyd Patterson won the middleweight crown in 1952.

He said: "I've matched my ambitions by getting a medal -- so now let's go for a silver or better."

The first Olympic Games Khan remembers was the last one, but now he is just one bout away from fighting for a coveted gold medal.

Asked about equalling Patterson's record, the youngster brought laughter at post-fight press conference. "Yes, I have heard of Floyd, er, is that his name?

"He won the gold medal at 17. I think I can do what he did, I'm sure I could as well. I just hope I perform well.

"It's a great achievement to win a bronze medal, the pressure is off me now,"

Khan's latest devastating display comes four days after he destroyed the European champion and he will fight Kazakhstan's Serik Yeleuov on Friday.

Promoter Frank Warren tipped Khan to become a professional boxing world champion who could earn millions from the sport.

"It was a fantastic performance," said Warren, who has managed an array of legendary fighters including Frank Bruno, Naseem Hamed and Nigel Benn.

"He could very well become one of our youngest Olympic gold medallists. He has got so much natural talent. Fighters like this come along once in a lifetime.

"He looks sensational now and he can only get better."
