Kell Brook has vowed to get the better of Gennady Golovkin in Saturday night's meeting as he attempts to dethrone the WBA Super, WBC and IBF world middleweight champion.
The 30-year-old has stepped up two weight divisions and weighed four pounds more than his opponent in Monday's final weigh-in ahead of the much-anticipated bout in London.
Brook admits that he is fearful over his meeting with the unbeaten unified world champion, but will use that to spur him on to a famous victory at the O2 Arena to maintain his own impressive unbeaten record.
"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," he told Sky Sports News.
"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."
Golovkin has a record of 32 knockouts in his 35 professional bouts, while Brook has 25 in 36 outings.
