Tyson Fury has no chance of losing to Francis Ngannou in the pair's exhibition fight this weekend.

That is according to former boxer turned promoter Oscar De La Hoya, who promised to quit his job if Ngannou pulls off a shock victory.

MMA fighter Ngannou, who has won 17 of his 20 professional fights, is making the move into boxing to face WBC heavyweight champion Fury in a lucrative exhibition bout in Saudi Arabia.

De La Hoya, though, is giving Ngannou little hope.

"As a boxing expert, as a fight expert, as a promoter now and as a boxing historian, if Ngannou beats Tyson Fury then I'll quit my job," De La Hoya told Stats Perform.

"And I love boxing, so I don't plan on quitting! 

"I think Tyson, inside a boxing ring, he's been in there with [Wladimir] Klitschko, he's been in there with [Deontay] Wilder, there's nothing that Ngannou can do to even make Tyson flinch. It's not going to be a good night for Ngannou."

Hall of Fame fighter De La Hoya is promoting Ryan Garcia, with whom he has had something of a complicated relationship. 

Garcia is going up against Oscar Duarte, and like his promoter, he does not see Ngannou having a chance against Fury, hitting out at the "crossover" fight.

"I'm sorry, I don't want to be disrespectful, but I don't see any reality where Ngannou wins," Garcia told Stats Perform.

"There's just no way. I'm a big fan of Fury and I think he's just an unbelievable fighter. He's beaten the best in boxing.

"I'm not going to think that a UFC guy is going to come in and beat him. It's just fun for the fans, man. 

"It's like these crossover TV shows where you get to watch your favourite cartoon being in another cartoon. That's all."
