WBO world middleweight title challenger Harry Simon is aiming to prove that he is one of the modern day greats by going up through the weight divisions and eventually challenging Newbridge's super-middleweight king Joe Calzaghe.

The first stage of Simon's plans for stardom takes place this Saturday when the undefeated Namibian challenges Sweden's champion Armand Krajnc for the WBO world title at the Cirkusbygningen Arena in Copenhagen, Denmark.

Already a superstar in Namibia, Simon wants to go on to prove that he is one of the sport's modern day greats.

"I want to follow the example set by previous greats like Sugar Ray Leonard, Thomas Hearns and Roberto Duran and more recently Oscar De La Hoya, Shane Mosley and Felix Trinidad by going up through the weight classes and challenging the champions," he said.

"By doing this and beating the best, I believe I will get the recognition I deserve." Providing 29-year-old Simon wins against Krajnc then he could be looking at a step up to the super-middleweight division for a mega-money showdown with the undefeated WBO world champion Calzaghe.

"The man I want is Calzaghe, he is the next stage of my plan after I beat Krajnc. I see the super-middleweight division as the ultimate test for me and I believe I can be a strong force at the weight.

"But first I must dispose of Krajnc before any of these plans can become real." Frank Warren, who promotes Simon and Calzaghe under the Sports Network banner, said: "This would be a tremendous fight for both men and for the fans. "Harry and Joe both have a huge desire to prove that they are the best and they are both, in their own rights, great fighters. I would love to see this fight take place and is a real possibility that it could happen."

Simon features in a joint top bill in Denmark along with Britain's Johnny Nelson who makes the 10th defence of his WBO world cruiserweight title against big-punching American Ezra Sellers.

Calzaghe also has a title defence coming up on Saturday, April 20, at the Cardiff International Arena. The Welshman faces his toughest fight since he won the world title against Chris Eubank in 1997 when he faces American dangerman Charles Brewer who is a two-time IBF champion.
