Anthony Joshua believes Wladimir Klitschko is the toughest opponent he has faced in his boxing career despite losing his belts to Oleksandr Usyk last year.
The British star suffered the second defeat of his career last year in a mandatory title defence against the Ukrainian. He had already been beaten by Andy Ruiz Jr in 2019, but later avenged his defeat by outpointing the Mexican in Saudi Arabia.
However Joshua maintains his fight with Klitschko came "too early" in his boxing career which made the epic battle his sternest test to date. "The hardest opponent I have come up against would be Wladimir Klitschko definitely," Joshua said during a Q&A with Oxford Union. "The passing of the guard. The young lion vs the old lion. At the time I fought him I thought it was definitely too early but it was his last fight.
