After Kell Brook agreed to battle Gennady Golovkin, here is a reminder of the Kazakh fighter's devastating punch power.
'The Special One' has stunned the boxing world by stepping up to challenge Golovkin for his world middleweight titles on September 10 at London's O2 Arena, live on Sky Sports Box Office.
Brook currently holds the IBF welterweight title and a 36-fight unbeaten record, but he is stepping up two weight divisions to face one of the most fearsome fighters in the world.
Golovkin's 35-fight unbeaten record includes 32 brutal stoppages and 'GGG' will be keen to add another knockout in his first fight in Britain.
He has already made a sickening impact on two domestic fighters as Matthew Macklin was halted by a brutal body shot in 2013, while Martin Murray was pounded to a halt in the 11th round of last year's fight.
