Liverpool cruiserweight boxer Tony Bellew has launched a torrent of abuse at former WBA Heavyweight World Champion David Haye, calling him a "failure" with regards to his attempts at making a career in Hollywood.
Bellew, who recently featured in the Hollywood sports film 'Creed', told Haye: "Listen David, you wish you were me.
"You wish you were me in that Hollywood movie. You went to Hollywood and failed. You went to Hollywood to try and crack it and failed. You've been living in nightclubs ever since."
The Liverpudlian continued by saying: "I am the first live fighter since Wladimir Klitschko and let's just get something straight, you didn't fight, you just danced and ran all night."
Haye - who is also a previous World Champion at cruiserweight - and Bellew, have agreed to fight one another at the heavyweight limit.
The fight will take place on March 4, 2017 at London's O2 arena.
After poking fun at Haye's hairstyle, Bellew then went on to make his predictions on how he feels the fight will pan out.
"It's quite simple, I hit him clean on the chin, he goes to sleep," he said via Sky Sports.
"I only need to hit him on the top of the chin, the top of the head, anywhere, other guys wobble and struggle, lesser guys than me.
"If I hit him clean he's going. But I am under no illusion that if he hits me first, I'm going too. This is high-class boxing and this is what happens when two punchers meet."
When discussing the possibility of the fight going on into the later rounds, the Cruiserweight Champion said: "The main thing is I get in there and if this fights gets down to guts and determination or anything that goes beyond four rounds, David is going to quit.
"David's going to b****, because that's what he is."
Ex-Heavyweight Champion Haye also has some words to say about the impending fight between the two Brits, and he also has some predictions about who will win the contest.
He said via the Guardian: “Even in his hometown of Liverpool, I would be stopped in the street by people begging me to spectacularly send him into retirement.
“Bellew is completely delusional if he thinks he can beat me. He still thinks he’s on the set of Creed and there will be some kind of Rocky-style happy ending. But come 4 March at The O2 in London I will bring reality crashing down on him.
“I’ve earned my credentials the hard way inside the ring, not on film sets.
"There will be no second takes, no stunt men taking the blows and no flashing lights on the red carpet, the only lights Bellew will see are those of the spot lights shining down on him when he wakes up from his nap on the canvas.”
