Croydon's world light-middleweight champion Wayne Alexander says the withdrawal of his opponent has not affected his preparation for his non-title fight on Saturday night.

The 31-year-old was set to face the former Belgian light-middleweight champion Douglas Bellini, but after his withdrawal last week he will be facing an as yet unnamed opponent at the ExCel in London.

Speaking to the Guardian from his training camp in Belfast, Alexander said: "It hasn't affected my preparation, I didn't really know who I was fighting anyway, I didn't know his strengths.

"But I feel I can beat anybody in the world, I don't care who I fight because I believe I am one of the best light-middleweights in the world."

Alexander feels he is in great shape for the fight after being put through a gruelling training regime by trainer John Breen over the past seven weeks.

Alexander said: "I've done an eight mile run over the mountains of Belfast, sparring, pad work and floor exercises as part of my training."

But Alexander can't wait to get in the ring again for the televised fight and be on the same televised under-card as his friend Danny Williams, who famously knocked out Mike Tyson last July and will be fighting Vitali Klitschko for the WBC world heavyweight title in New York on the same night.

Alexander said: "Danny is a good mate of mine, we turned professional on the same day with Frank Warren, so I'll be watching his fight after mine."
