CARL FROCH has dubbed Jake Paul's promotional partner a "clown managing a clown" as the war of words continues.
Froch, who retired in 2014, has embarked on an outspoken punditry career since hanging up the gloves.
And YouTuber-turned-boxer Paul has been among the most criticised by the British legend.
Even his business partner Nakisa Bidarian has faced the verbal wrath of Froch and he unloaded once more on his .
Froch said: "Right, Nakisa is Jake Paul's manager.
"This guy is an absolute clown, it's a clown managing a clown in the fake world, in the clown world that is Jake Paul pretending to be a professional fighter.

"We'll call him Fake Paul from here on in because he's not real, is he? He's a fake boxer. But Nakisa said I'm "irrelevant."
"I've straightened him out, I've already said that I'm not irrelevant and I've invited him on the show. And guess what? He's declined.
"He doesn't want to come on the show because he knows The Cobra speaks facts and he tells it how it is. Shoots from the hip.
"Nakisa cannot come on the show because he knows as soon as I say to him, you're convinced Jake Paul is going to become world champion, who is he going to fight for a world title?

"As soon as I ask him the question about Jake Paul becoming a world champion, he's going to hit a brick wall because Fake Paul is never going to become a world champion.
"He's got that f***ing plastic Toys R US belt that Nakisa gave him and that just about sums up Jake Paul's career, a fake world title belt."
Froch retired in 2014 after knocking out George Groves in front of 80,000 fans at Wembley Stadium.
But he has called out Paul and vowed to fight for FREE by donating his purse to charity.
Bidarian - who is not officially Paul's manager but instead a business and promotional partner - hit back with their terms.
He told SunSport: "Sure Carl, show up with an offer that makes sense - since he's fighting for charity anyways - he's made it clear that he's going to donate 100 per cent of his earnings to charity.
"Show up with an offer that makes sense for MVP and Jake Paul, who drive the biggest numbers in the entire sport and we'll have happy to have a conversation.
"We'll call him Fake Paul from here on in because he's not real, is he? He's a fake boxer.

"We're certainly not looking to come to the UK to offer a 47-year-old Carl Froch -who's never sold a pay-per-view in his life in the US which is the most important market - and make him an offer.

"And, he's fighting for charity anyways, he's fighting for free. So, if and when they're ready to show us an offer that shows that he's 100 per cent donating all proceeds that he gets paid and any entities associated with him to charity...
"And that it is an eight-figure opportunity for Jake Paul - which is what Jake Paul makes in every single fight - happy to have the conversation. Absolutely."
