The 30 year-old puts his unbeaten record on the line against one of the hardest punchers of recent times in London and admits that there’s no margin for error when he trades blows with Golovkin at The O2.
“I’ve got to box the perfect fight. Anything short of that and it’s not going to look good for me,” Brook told Sky Sports News HQ.
“I’ve got to make sure I do things first, get the jab established first. I can’t just go out there and have a war with this guy because he’s a big strong guy. He’s also smart and I’ve got to box the perfect fight. I’ve got to do what he doesn’t want me to do.”
Asked about where a victory would leave him, Brook added: “A win puts me as the best fighter on the planet, pound for pound and in every weight division.
“No-one is giving me a chance in this fight and that’s what I thrive off. That’s what gets me up in the morning and makes me train my socks off.
“I’m so focused on this fight and I’m making history to leave an absolutely fantastic legacy whilst I was in the game,” he said.
Golovkin, 34, has stopped 32 of 35 opponents inside schedule and has never been taken the twelve round limit.
Brook’s fellow countryman Martin Murray pushed Golovkin to eleven rounds in February 2015, although was forced to soak up a massive amount of punishment before being saved by referee Luis Pabon in Monaco.
