ANTHONY Joshua faces his biggest challenge on Saturday at Wembley Stadium.
In front a partisan crowd of 90,000 he comes up against Ukrainian giant Wladimir Klitschko, considered one of the greatest heavyweights of all time.
The prize, THREE heavyweight world titles — the IBF one he is defending as well as crowns from the IBO and WBA.
Anthony, 27, promises to “unleash hell” against Klitschko, 41 — who like himself, towers 6ft 6in tall.
A purse of some £15million awaits each fighter, win or lose, in a battle expected to smash pay-per-view records and gross a total heading towards £50million — making it the most lucrative in UK history.
The pair are well-matched physically.
Both are 6ft 6in tall, and have a similar reach, Joshua just nicking it at 82ins to Klitschko’s 81ins.
Joshua has a perfect professional record since leaving the amateur ranks following his Olympic gold medal at super-heavyweight at London 2012, with 18 wins and 18 KOs in 18 fights.
In contrast Klitschko, who also won Olympic gold medal at super-heavyweight at Atlanta in 1996, has fought 68 times as a professional.
