WBA, IBF junior middleweight champion Jarrett Hurd (22-0, 15 KOs) is annoyed with some of the trash talking that he's heard from the mouth of Kell Brook (37-2, 26 KOs), who previously held the IBF title at welterweight.
Brook, in several interviews, questioned the worth and in-ring abilities of the unified beltholder.
Hurd had his career best performance last month, when he won a twelve round unanimous decision over division ruler Erislandy Lara to unify the WBA, IBF belts in Las Vegas.
Brook officially made his move to the junior middleweight division back in March, when he blasted out Sergey Rabchenko in two rounds.
It was Brook's first win after suffering back to back stoppage defeats at the hands of Gennady Golovkin and Errol Spence.
"I was watching a few interviews on YouTube with Kell Brook saying a few things like 'the kid Hurd's not that good', and he'd fight me if there was a belt on the line," Hurd told Sky Sports.
"Not only does he say he would fight me if there was one belt on the line because I am no good, well I've got three belts. If he wants to show he is up for the challenge, I've got the opportunity for him."
Hurd is waiting for the outcome of next month's fight between WBC champion Jermell Charlo and challenger Austin Trout.
Should Charlo win, there is a very good chance that he will face Hurd in the fall.
Hurd believes his advantage in size, strength and workrate will power him right past Brook. He sees nothing that Brook can do to prevent his incoming charge.
"Of course, I want all the belts. We don't want pushovers though, or no easy fights, just tough fights to set up the unification with Jermell Charlo. That's why we want Kell Brook," Hurd said.
"Right now he's not a natural 147-pounder, he's a little smaller but he is a decent fighter. The tools that he has are not very specific and he does nothing extraordinary but does nothing bad either.
"I've got my size advantage and just me, who I am... the No1 unified champion. Anything I can do in the ring I capitalise on, I can walk Kell down, it doesn't matter, nothing he can do can neutralise anything I've got."
