David Haye made himself known to Wladimir and Vitali Klitschko two years ago with an inflammatory but humorous t-shirt showing him standing over the decapitated corpses of the two brothers.
Wladimir Klitschko recently claimed that David Haye may have regretted this and made a big mistake.
Could Wladimir have been any more wrong?
This week Haye opened up his training camp to the media and has shown himself to be fighting in preparation for his encounter with Wladimir Klitschko on July 2nd in Hamburg, Germany. The Hayemaker was happy to tell everyone that he is training harder for this fight than any other.
Haye was also keen to highlight that this has been the least stressful build-up to a fight he has ever had.
Haye and his trainer Adam Booth, the ominously titled 'Dark Lord', believe that Klitschko will struggle with a 'new strategy' that they have developed.
Booth has recently proven himself to be a decent tactician, with his young fighter George Groves defeating heavily favoured James DeGale in a points decision.
However, just to be sure, Haye is trying to use mind-games in order to unsettle Klitschko. David Haye's Knockout for mobile phones allows the player to fight an unnamed Russian opponent.
It's hard not to notice the thinly veiled attempt by Haye to disguise the fact that it's Klitschko as the opponent. For the record, Klitschko is actually Ukrainian.
In his own build-up to the fight, Klitschko has been very friendly to the media and fans everywhere. It's hard not to see Klitschko other than as the perfect gentleman.
Haye has avoided being gentlemanly to ensure he is not distracted by someone that he has become too friendly with. Pacquiao and Mosley immediately spring to mind.
Haye is trying to unsettle Klitschko, and his latest stunt is possibly to ensure that the Ukrainian giant comes into the ring with too much red mist in his head.
Klitschko has always been highly disciplined in his approach, often to the extent that he fights too cautiously. Haye's goal may be to get inside the mind of Klitschko so that he loses that discipline enough for Haye to find holes in his defence and attack his chin.
In the meantime, maybe Klitschko will take time out to beat himself up on Haye's new game.
