Kell Brook is in for the fight of his life this Saturday at the O2 Arena when he faces Gennady Golovkin for the WBC, IBF, and IBO middleweight titles.
As if fighting GGG wasn't a tall order in itself, Special K is jumping up two weight divisions to do so.
Both men are unbeaten in their professional careers, but Golovkin is known as one of the most vicious knockout boxers in the world today. He has dimmed the lights on 32 of his 35 beaten opponents and Brook isn't being given much chance against the Kazakh middleweight king.

Promoter Eddie Hearn told the media on Thursday that he doesn't think the 30-year-old from Sheffield is all there in the head.
“He’s not the full ticket. That’s the only way you can describe Kell. He’s got no fear in him. He knows the dangers of the fight but he is buzzing.
"He’s just so happy he’s going to get a chance to show what he can do. I know this is a huge challenge, but I don’t think this fight is going to play out the way people are scripting it.”
Brook is no walkover, and on this occasion, he will not have to drop weight to make sure he adheres to the 10st 7lb welterweight limit, of which he is the IBF champion.
“You are going to see me at my peak. Before I have fought 60-70%, but this time I will be at 100%. There is some fear with me in this fight but it is going to make me so sharp and switched on.”
Brook hasn't hasn't fought a true top calibre fighter yet and although his courage is to be admired, he's more than likely to get a rude awakening on Saturday night.
