IBF welterweight champion Kell Brook (35-0, 24KOs) is motivated to do a real job on Diego Chaves when they step in the ring later this year. The fight was scheduled for this past Saturday, but Brook picked up a rib injury in camp and withdrew from the bout a week ago.

The opponent initially pursued was former champion Brandon Rios. The two sides were unable to reach an agreement on several of the terms, leading to Rios' withdrawal from the discussions and then Brook decided on Chaves.

During a recent interview, Rios verbally assaulted Brook. He said the Sheffield fighter would get battered by just about every top boxer in the welterweight division.

Brook brushed off those comments and said Rios was confused as to the facts of the matter.

He feels confident that his in-ring performance, when he finally faces Chaves, will skyrocket his worth in the welterweight division. 

"I think I've seen what he [Rios] said and I am telling you now, I am the best welterweight on the planet," he told Sky Sports.

"There's no welterweight out there who can beat me. He can say I am scared of any other fighter and he can say this or that. I am just sorry for all the fans in Sheffield who were going to turn out and see me on Saturday. I was going to do [to Chaves] what no one else has done.

"It's just going to have to wait a little bit longer, but when I release what I am going to release on fight night, you're going to know that no welterweight can touch me."
