Kell Brook thinks the fear factor of fighting Gennady Golovkin will give him that extra edge come fight night on Saturday.
Sheffield-born star Brook faces Golovkin for his WBA Super, WBC and IBF world middleweight belts at the O2 Arena this weekend.
The 30-year-old is stepping up two weight divisions to take on the Kazakhstani and Brook remained defiant in the final press conference before the bout – promising to “shock the world”.
The IBF welterweight champion said: “There is fear in me over this fight but that’s going to make me so sharp on the night. Having that fear is healthy. It’s good for me to be sharp and switched on throughout the fight.
“The talking is over. The training is over. It’s coming down to two champions, two top fighters fighting each other on Saturday night and I can’t wait to shock the world.”
A lot has been made of Brook stepping up in weight but the fighter believes that it’s “written” that he beats Golovkin.
“I’m in great shape. I pushed myself through every training session and I’m passionate about doing something no British fighter’s have done. I believe it will be the biggest win ever,” Brook added.
“I think I’ve got the skills. Everyone is going on that I’m a small guy coming up but that’s not the case. I’ve never trained like I’ve trained for this with the calories and the fuel. I’ve been a joy to train and have been able to dig in and go past what I’ve done before.
“Coming into this fight, I’m healthy and strong. I believe it’s written and I really do believe this is my time.
“We aren’t taking ridiculous amounts of weight off to make 147lbs. I’ve probably been 60-70 per cent in my career and we’re going to see 100 per cent on Saturday.”
