Kell Brook says he will deal with the challenge of Diego Chaves and show he belongs at the top of the welterweight division.
Brook will make the third defence of his IBF world title against Chaves on October 24 at Sheffield Arena.
The Argentine has won just one of his last four fights but has mixed in elite company during that time.
Chaves has lost to Brandon Rios and Keith Thurman in the last two years.
But his most impressive recent performance came last time out when he battled out a draw with Timothy Bradley, widely regarded as Brook’s main rival to be the world’s top welterweight after Floyd Mayweather’s retirement.
And Brook is well aware what a win and a strong performance against Chaves will do for his career as he looks to land welterweight super fights.
“I’m looking to make a mark in this fight and show I’m a cut above in this division,” Brook said.
“This guy is going to be a big test for me and I’m going to show how good I am.
“He’s got that draw with Timothy Bradley. He comes to fight, he’s a warrior who leaves it all in the ring.
“He’s knocked plenty of kids out so it should be exciting. I’m going to bring it as well. The fans are in for a treat.”
Chaves – who has stopped 19 fighters in his 23 wins – is confident he will cause an upset when he faces Brook.
And he says he provide a big test of Brook’s punching power. “We know Brook is a tough fighter, very technical,” Chaves said.
“He is a linear fighter, very frontal. He’s not a fast fighter. He is easily bothered by body punches, and that is one of our strengths.
“And I believe he has problems going backwards.
“But we know that he is a great fighter to face, and we are going to test his punching power too, because the opponents he chose so far have not been such great punchers as the ones I have faced lately.
Tickets for the October 24 bill go on sale on Monday.
