John Fury is 'irritated' that Mike Tyson is training Francis Ngannou

But not everyone is happy about Tyson training with Ngannou.

And that someone is Fury's father, John Fury.

"Irritating. I named my son after this man and he’s in his opponent's corner," John told talkSPORT via freebets.com. "But that’s business and the business of the game we’re in. Would I want him in Tyson’s corner, yes I would, but he’s a grown man and can make his own decisions."

Ngannou will be fighting Fury in Saudi Arabia for his boxing debut. If he wins, he'd be the first big MMA to boxing crossover who defeated the legitimate boxer. Many MMA fighters have tried and failed in past. Names like Conor McGregor, Ben Askren, Tyron Woodely, and Anderson Silva. Ngannou doesn't want his name added to that list.

Bob Arum thinks Francis Ngannou is a 'tremendous puncher'

Bob Arum, Top Rank CEO, had high praise for Ngannou.

"Absolutely this is a more dangerous fight!" Arum told Pro Boxing Fans. "Ngannou hits harder than either Chisora or Dillian Whyte, and when you’re in with a puncher like that, and you’re not in perfect shape, that’s when you can get knocked out. Ngannou is a tremendous puncher, probably the best puncher in the history of the UFC. This is going to be a really interesting fight. It’s going to be very fun to watch.”

Francis Ngannou thinks Tyson Fury is 'cheating'

While speaking to Joe Rogan, Ngannou accused Fury of cheating by manipulating his gloves.

"He’s very tricky with his glove. I think he cheats," Ngannou recently told Joe Rogan. "We are talking about it with the team, and they’re like, ‘Oh, there’s the UK commission with the gloves.' I’m like, ‘Bro, we’re going to get there, we need every glove to be checked."

He doubled down on those thoughts during his open workout, joking with media that he'll be watching his gloves.

The fight will take place on October 28, Fury's title will not be on the line.
