Wladimir Klitschko, who has had hands on experience with both Anthony Joshua and Deontay Wilde in recent years, believes the Brit could struggle against the American, if they face off later this year, the Daily Express report.
Klitschko has previously sparred with Wilder back in 2014 and has taken on Joshua in a fight which lasted 11 rounds at Wembley, with the Ukranian retiring after the defeat in London.
Asked about a potential meeting between Joshua and Wilder, Klitschko said:
It would be a dangerous fight for Anthony Joshua, I’m not saying he wouldn’t win it but Wilder has something. Due to his weight, he is extremely fast. He has good power in his hands and he’s extremely fast.
Joshua’s camp believe they are only a few weeks away from announcing a fight against Wilder, with rumours suggesting it could take place as soon as September at Wembley Stadium.
If the clash does take place, the winner would become the undisputed heavyweight champion of the world, with Joshua now the holder of the WBO title after defeating Joseph Parker on points in Cardiff last month.
The meeting with Parker was the first time Joshua had been taken the distance in his professional career, with Klitschko admitting a meeting with Wilder could also go the distance.
