Former two division world champion David Haye has given his take for the upcoming clash between Deontay Wilder and Tyson Fury.

Haye was at one time scheduled to fight Fury on two separate dates, a few years ago, and withdrew from both bouts with injuries.

And ironically for one of those contests, Haye had used Wilder as one of his main sparring partners.

Haye has a lot of respect for the punching power of Wilder, which the former WBA heavyweight champion explains was very evident even when sparring with bigger gloves and head guards.

"I sparred many rounds with him and I had to be switched on as much I was switched on for a fight. Normally in sparring, you’re giving it about 80-90%, a shot comes you’re wearing big gloves, head guards but with Wilder you have to be on your game otherwise he can hit you and hurt you," Haye said to Fighthype.com.

"In sparring you can go 80-90% as head guards are worn but with Wilder you have to be on guard 100% otherwise he will seriously hurt you.”

Last weekend in Belfast, it was officially announced that a deal was finalized for Fury (27-0, 19 KOs) to challenge Wilder (40-0, 39 KOs) for his WBC world title in the fall, likely on a November date in Las Vegas.

Fury had the second fight of his comeback last Saturday night, when he dominated Francesco Pianteta over ten rounds of action. Wilder was sitting at ringside and then went face to face with Fury in the aftermath.

Fury had been inactive since November of 2015, when he traveled to Germany to upset Wladimir Klitschko to capture the unified crown.

The "Gypsy King" finally returned to the ring in June of this year, when he stopped Sefer Seferi in four rounds.

“Wilder is the most dangerous one-punch hitter on the planet right now. Whatever you think about Tyson Fury, you have to give him the utmost respect and he’s willing to put it on the line,” Haye said.
