After an improved performance against Usyk, Joshua tossed two of his belts out of the ring and looked to storm backstage before returning to the ring to launch into expletive-laden outburst.
The Brit was criticised for his behaviour, with many believing it was the champion’s moment to celebrate.
Still, Usyk insists he holds no ill-feeling towards the 32-year-old and even hinted at a trilogy fight should he not meet Fury in what would be a hugely anticipated undisputed bout.
"I don’t hold a grudge against him,” he said.
“He was upset. I’d be upset if I lost twice. Joshua has potential to grow, he needs to get some people away from him because he has a lot of freeloaders. Joshua is a handsome man, well done.
“I don’t want to talk about the competence of the judges, but when I watched the rematch with Anthony Joshua, I can say that four, well, a maximum of five rounds can be given to Joshua.
“If Fury floats away, then maybe we will agree on a third fight with Joshua.”
