He first edged past Paul via split-decision last February in Saudi Arabia before moving onto a mega-fight with KSI.

But the build-up was marred in bitterness and KSI even spat gum at John during an open workout.

Son Tommy went onto win a controversial six-round decision but still tension remains between the two camps.

John told the Daily Mail, via Free Bets: “We’re not interested in KSI. Not for a trillion dollars.

“Unless he comes up with an apology and decides to be a man, we want no part of it.

“He lost to Tommy on his own show. I know he’s aged about 10 or 15 years because of it. People like him, their egos are so big they just can’t move on from it.

“That will be his downfall. He needs to look in the mirror and take some lessons off real men on how to be one. You can’t disrespect people think you’re it.

“At the end of the day, up until the spitting job, up until the BS, he was doing a great job. Him and Logan Paul.

“But, at the end of the day, Pauls are a different class to him. They’re not spitting at people. They are having verbal disagreements. That’s all part of the game.

“Spitting at people is a reptiles job. That’s something the scum of the earth does.

“I am no posh person, I am probably one step off the bottom but I don’t spit at people. I don’t disrespect people in that way.

“It becomes hatred and no one can do their job properly then.”

KSI, 30, announced he would take time out from boxing following his first loss but has since revealed he will fight again this year.

Meanwhile Fury, 24, has undergone hand surgery for an injury in which he said has hampered him for four years.

Paul, 27, bounced back from his defeat with two wins and returns on March 2 on the undercard of Amanda Serrano’s Puerto Rico homecoming.

But he revealed talks with the Fury family are back underway.

And John added: “We spoke to them about six weeks ago and we’ve not heard anything since.

“I’m not sure what is going on behind the scenes. But, the buck stops with me. Right here.

“People can say what they want and do what they want, but the bottom line is that it has to go through me and Tommy.”
