Watching from his training camp vantage point in Kyrenia, Northern Cyprus, world heavyweight title contender David Haye will have studied every minute of the eight rounds it took for incumbent World Boxing Council heavyweight Samuel Peter to be out-thought, out-fought and ultimately outclassed in Berlin by Vitali Klitschko on Saturday night.

‘Dr Ironfist’ is back. The heavy division is heating up. And Haye insists he can defeat both Klitschko brothers, disclosing to Telegraph Sport that he has the style – and speed - to unseat both champions, who now share three of the four major sanctioning body belts. The fighting Klitschkos have become the first boxing brothers in history to simultaneously hold heavyweight world title belts. The only belt outside their grasp is the WBA title, held by giant Russian Nicolay Valuev.

Ask Haye, and he’ll happily fell all three giants. Haye, who debuts as a heavyweight bill-topper at the 02 Arena, Greenwich on November 15, against American Monte Barrett, is convinced he has “the tools to defeat both Klitschkos”.

Haye said: “Give me Wladimir first, then I’ll take on the older brother. Neither of them has the speed I can show them, and they are both vulnerable.”
