British cruiserweight champion Isaac Chamberlain hit out at the English champion, Viddal Riley.
Riley is best known for training KSI in previous years, but defended his belt against Mikael Lawal on points at the weekend.
Speaking to Sky Sports , Chamberlain said he was unimpressed.
He said: "You're just running and peppering, trying to pepper and using some fake double jab to get away. Bro, at least just plant your feet once and lamp him.
"This is professional boxing, this is not the amateurs. You can't just be doing some dancing thing and thinking people are going to enjoy that."
Chamberlain thought his own performance against Lawal, winning by a unanimous decision, was much more impressive.
"I literally tried to negate everything. I shut him down up close, I pushed him back," Chamberlain said.
"[Riley] was just running and going backwards, backwards the whole time. Me, I was forcing it on Lawal, pushing the pace, pushing the pace, feinting all of that.
"He thought he could do that but he probably couldn't."
He added: "If he fights me like that, I'll break him.”
