LONDON (AFP) WBA world heavyweight champion David Haye has scoffed at comments from his next challenger Audley Harrison that he had been knocked down while sparring for their forthcoming fight. The British rivals have been trading barbs over the last few weeks as they prepare for their big fight in Manchester on November 13. The latest round of charges came when former Olympic champion Harrison claimed that Haye had been decked in training by sparring partner and former world title challenger Tony Thompson. But Haye, who will be making the second defence of his WBA title, insists the Olympic gold medallist is delusional. Im hoping he takes it on board because hes looking for things to give him a mental advantage. If he wants to believe I got knocked down in sparring, then keep believing it. If thats going to make him sleep a bit better at night then go for it. Tell him I got knocked down 500 times in sparring if that makes him feel better. I know it didnt happen and its irrelevant. The guys delusional, he seriously is. Harrison had stated: They brought Tony Thompson in, hes a world-class heavyweight, but hes not a puncher. If Tony Thompsons putting David Haye out...I already know thats going to happen in this fight. Haye is overwhelming favourite to retain his crown at the MEN Arena and has warned Harrison he will feed on his psychological demons. Im glad Audleys having his time in the spotlight and is getting some column inches, he said. Hopefully hell take all these newspaper clippings and make a book of them so that when he slinks back off to LA he can have a look at them.
