IBF, IBO, WBA, WBO heavyweight champion Anthony Joshua is hoping that his upcoming opponent, Kubrat Pulev, backs up his talk come fight night.
On Saturday night, Joshua will make a mandatory defense against Pulev at the SSE Arena in Wembley.
The two boxers nearly brawled it out on Friday, at the official weigh-in.
After trading heated words, they had to be pulled apart by security.
Pulev has one defeat on his record, which stretches back to 2014 - when he suffered a knockout loss at the hands of then unified world champion Wladimir Klitschko.
The two boxers were initially set to collide back in 2017, but Pulev was forced to withdraw due to a shoulder injury. He was replaced by Carlos Takam, who Joshua stopped in a tough fight.
Pulev got himself back in position as the mandatory challenger, with the fight being booked for this past June. It was postponed due to the coronavirus pandemic.
Now they finally get the opportunity to settle the score - after nearly trading punches at the weigh-in.
"I don’t know what sparked that. That’s just how we are. He has spoken a lot of rubbish and now he has to back it up. I have seen so many fighters talk a load of rubbish and then get smacked up. If you don’t know boxing then that sort of thing could intimidate you but I could have whacked him up there but I have to save it for tomorrow," Joshua said.
"I have studied him and he thinks he is a warrior but he is up against a real one now. When people come in the ring with me they are confident but I take their soul away and get them out of there."
