Golovkin relishing challenge and planning hot reception for Brook
Gennady Golovkin has a serious plan for his upcoming middleweight title fight with Kell Brook, who he has labelled as the biggest challenge of his career.
Golovkin will aim to take his professional record to 36-0 when he defends his WBC, IBF and IBO middleweight titles on Saturday at London's O2 Arena against IBF welterweight champion Brook, who goes into his 37th career bout also still yet to taste defeat.
The Kazakh goes into the fight as heavy favourite with Brook having jumped up two weight classes, but Golovkin is wary of the threat posed by his British opponent.
Golovkin said: "He looks good. He looks strong and big. It's very serious and it's a huge fight.
"My first question to my coach was about (Brook having) different speed but he said no - just different size, different power and different timing. I thought 'Wow'. It's interesting.
"He's my biggest fight and my biggest challenge. It's my biggest step.
"I feel great. I feel it's time to fight. I have to thank my coach, Abel Sanchez, who brought a new strategy for this.
"It feels great. I feel different and I feel good. I have a different plan and a more serious plan."
