GENNADY GOLOVKIN feels Kell Brook will be the “biggest test” of his glittering career to date  when they meet on September 10.

Brook, holder of the IBF world welterweight title, will be jumping two weight classes to take on the Kazakh wrecking ball.

Golovkin, who already holds cult status in the UK, is excited to box in England for the first time.

“I’m very excited, I’m very happy to be here,” he said.

“I can give true fans, UK fans, an amazing event. This is the biggest fight for us, I respect Kell, he has a very good team.

“I understand this isn’t easy, this is very serious business for us. I’m ready 100 per cent, I believe I bring amazing show, a big event, big drama show.

“This is the biggest test for mme. Kell is a true champion, right now he’s coming to middleweight. I remember Manny Pacquiao’s fight with [Antonio] margarito, [Oscar] De La Hoya. This is the biggest test for me.

“I’m not scared, I understand this is business. I respect sport, I respect boxing. This is a chance to bring a present to the UK.”

Brook, the unbeaten Sheffield star, is installed as a significant underdog for the first time in his paid career.

However, the smart boxer-puncher is not fazed by the odds and is ready to capitalise on the biggest opportunity of his life.

“It’s the biggest fight in world boxing. It’s a fight that makes me so excited, I’m the best welterweight on the planet and nobody wants to fight me, it’s the same with ‘GGG’,” he said.

“We’re bringing up speed but we’re also getting the right numbers with power at the new weight. I’m going to be so sharp, so alive on the night.

“Nobody’s ever got the best out of me, I want to test myself and I know that we’ll see he best in me. I’m excited myself to see what I can do. I always seem to do enough, find a way to win, and it’ll be the same. There’ll be massive drama.

“People go on about weight, Mike Tyson wasn’t the biggest heavyweight and he was an animal. 160 is my natural weight, it’ll be the best of me. I’m very healthy, well hydrated, I’m training like a wild horse.

“I want to go down, like my hero Sugar Ray Robinson, in history.”

Dominic Ingle, Brook’s trainer, understands the task ahead of his charge but is supremely confident with around six weeks to go.

“We’ve had a great camp so far, Kell can get down to the hard work. Hopefully next week we’ll start sparring. Kell Brook will get into the ring on September 10 in the best shape of his life, and he’ll need to be,” he said.

“We’ve looked at Golovkin, we’ve got a plan in mind, so we just need to implement it. It’s a big ask, people will say it’s not possible, but Kell Brook will become the middleweight chamion of the world.

“Kell’s got to mindful of what’s coming at him, we’ve addressed all the scenarios.”

Golovkin’s trainer, Abel Sanchez, knows plenty about Brook and expects a great fight.

“I know that Kell’s improved a lot, we’re looking foward to a hard fight against the best welterweight in the world,” he said.

“Hopefully it’ll be the type of fight the fans expect. Guys like Golovkin and Kell are very cerebral, and that makes for a great fight. That fear will become aggression, that intelligence will become motivation.

The great ones, it’s about the intelligence they possess.”
