Usyk retained his WBA, WBO, IBF and IBO heavyweight titles with a split-decision victory over Britain’s Joshua, who fared higher within the rematch however proved unable to dethrone the champion in an absorbing 12-round contest.
“It’s really, really hard for me to say I’m proud of myself. I’m upset, really, deep down in my heart,” Joshua instructed reporters.
“I tried a different style … in the last fight I wanted to compete as a boxer, but it wasn’t good enough, and tonight wasn’t good enough.”
Joshua threw down two of Usyk’s belts after the ultimate bell earlier than storming out of the ring, solely to return later and ship an impassioned speech.
“When you try and do things from your heart, not everyone is going to understand,” defined Joshua. “It was just from the heart. I knew I was mad at myself. Not at anyone, just myself. I was like I got to get out here because I’m mad.
“When you are indignant you would possibly do silly issues. Then I realised that is sport. I got here back and did the best factor.”
Joshua’s promoter Eddie Hearn dismissed speculation that retirement may be around the corner for the 32-year-old, who has only fought Usyk since last year.
“I’m a fighter for all times. That starvation by no means dies. Fighter for all times,” Joshua mentioned.
