2003 he won seven fights, two of which were the only fights he has fought in the United States. He won all by knockout (KO), the most notable being a fourth-round KO of Lolenga Mock, in which Haye had to come off the floor to win. Haye's fights were regularly seen on the BBC and his popularity began to grow in 2004, when he dispatched the 39-year-old former world champion "King" Arthur Williams in three rounds. Haye vs. Thompson Later that year, in his eleventh fight, he fought 40-year-old former WBO champion Carl Thompson in a 'youth vs. experience' match-up. Haye started fast and alarmingly caught Thompson with constant barrages of power punches, coming close to forcing a stoppage at numerous points over the first few rounds. Gradually, despite the early punishment he received, Thompson warmed up and worked his way into the fight whilst Haye seemed to tire and slow down. Thompson began to pressure Haye and knocked Haye down with a chopping right hand in round five.

Haye easily knocked out Gurov with a single right hand in just 45 seconds. Haye vs. Fragomeni In January 2006, Haye signed a three-year contract with former Lennox Lewis promoter Frank Maloney to further his world title ambitions. He successfully defended his European title against Ismail Abdoul in a lopsided twelve-round decision. He defeated Giacobbe Fragomeni, when he broke through the Italian's defences in the ninth round, finally flooring his man in a flurry of punches. Haye had waited seven years for the opportunity to defeat Fragomeni, who controversially out-pointed him as an amateur in the final qualifying tournament for the Sydney Games. Haye's cameo at heavyweight in April 2007 resulted in a first-round KO win over Polish fighter Tomasz Bonin, who at the time was ranked No. 9 by the WBC and had only one loss, against Audley Harrison. Haye admitted he was taking "a
