IBF welterweight champion Kell Brook (36-1, 25 KOs) is a man on a mission.

The tough fighter is very motivated to make a statement against his mandatory challenger, unbeaten United States Olympian Errol Spence (21-0, 18 KOs).

A deal between the boxers was reached a few weeks ago. The fight with Spence is going to take place in late May, likely on May 27, in Brook's hometown of Sheffield.

In his last fight, Brook moved up by two weight divisions to challenge IBF, IBO, WBA, WBC middleweight champion Gennady Golovkin last September at the O2 Arena in London.

Brook did well in the fight, but suffered a fractured orbital bone and was stopped in the fifth round. He underwent surgery and remained out of the ring for several months to recover.

Brook believes that he hasn't received the proper respect from the American boxing fans, after he traveled over to Los Angeles in 2014 to win a close twelve round decision over Shawn Porter to capture the IBF belt.

He wants to get that respect from the U.S. fans, because many of them are backing Spence to not only win but to win in style.

"I still got that fire burning deep inside. I'm looking forward to putting a showing that I'm the Special One. I think once I do the job on Errol Spence, the Americans are going to know.... because I don’t think that I’ve got the credit I deserve. I think this is going to be the fight that kind of puts me number one on the pound-for-pound list as the best fighter out there in the world," Brook told Scotty Silver of Scott TV.

"Them Yanks. When I boxed Shawn Porter... they really go over the top the Americans. I think it's well known that they really hype a job up, they really [do]. With Jeff Lacy back in the day when he boxed Joe Calzaghe - he was the best thing since sliced bread. Then he came over and got a master class from Joe Calzaghe. He made [Lacy] look like an amateur. People don’t realize that when the real Kell Brook turns up - I’m a monster. I showed that in my last fight against Golovkin with the eye injury. I put a show on."

"No one has ever done what I did to Golovkin, and he’s a big middleweight that walks through everybody. I just think he’s going to bring the best out of me, Errol Spence, because he is a talented kid. But nobody has seen how good this guy really is, and I hope that I bring the best out of him."
