Paul Butler believes he is currently preparing for the 'toughest task in boxing' with his showdown against Naoya Inoue just weeks away.
WBO title holder Butler travels to Japan to face Inoue in Tokyo on December 13, with the winner of the historic bout set to become boxing’s first undisputed bantamweight champion in half a century. Nicknamed the 'Monster', Inoue holds the IBF, WBA and WBC belts and wants to clean up the division before moving up in weight – but two-time world champion Butler holds the missing piece of the puzzle.
Inoue made history back in June when he beat Nonito Donaire in a second-round technical knockout to became the first Japanese boxer to hold a world title from three different sanctioning bodies in a single weight division. Butler (34-2, 15 KOs), who won the WBO interim title in April with a unanimous points victory over Jonas Sultan at Probellum Liverpool, was then upgraded to full champion after John Riel Casimero was stripped of the belt.
