The heavyweight champion produced a devastating knockout in the ninth round to retain his IBF, WBO and WBA belts but attention quickly turned to the possibility of a unification bout with Fury. Joshua seemed reluctant to talk about his rival at first but fans roared with approval when asked if they’d like to see the two face off. “I started this game in 2013. I’ve been chasing all the belts. I’ve been dealing with mandatories,” Joshua told Sky Sports when asked about a potential fight.”Of course I want the challenge. It’s not about the opponent, it’s about the legacy and the belt. “Whoever has got the belt, I would love to compete with them. If that is Tyson Fury, let it be Tyson Fury. It’s no big deal.”It’s one fight at a time, picking them off one by one. That’s all it’s about for me. I’ve got to stay focused.”READ: How Tyson Fury stunned Deontay Wilder and who is next for the ‘Gypsy King”The biggest fight in boxing’Fury is the current WBC champion and took to social media to call out Joshua after the fight, predicting he’d stop the 31-year-old within three rounds. “I want the fight.

The Bulgarian, who has now lost just twice in his career, continued to smile at Joshua despite being pummeled by the champion and deserves credit for taking the fight as far as he did. But Joshua, who deployed his trademark uppercut to good effect throughout, eventually wore his opponent down and knocked him out in the ninth round with a devastating straight right hand. Joshua has now won 24 out of his 25 fights, with his only loss coming against Andy Ruiz in 2019.
