Boxing's knockout king Gennady Golovkin has claimed he now wants to beat his next opponent by going all 12 rounds, rather than inflict the 30th stoppage of his burgeoning career. The Kazakh warrior is on the brink of becoming boxing's next superstar after causing a trail of destruction. In his 32-fight career, Golovkin has 29 knockouts, meaning his 90.6 per cent KO rate is the highest in the history of the middleweight division. Golovkin's next opponent will be Willie Monroe Jnr on May 16 in Inglewood, California - just three months after his latest brutal KO, of Britain's Martin Murray in Monaco. And the IBO/WBA and WBC interim middleweight champion said he hoped to be taken the distance for the first time in 20 fights and seven years.Gennady Golovkin fights Willie Monroe Jnr in MayThe Kazakh is hardest pound-for-pound puncher is boxingBut he wants to prove his greatness by winning over the full distanceGolovkin wants unification fight against WBC champion Miguel Cotto
