• Japanese boxer wants to fight Briton ‘any time and anywhere’
• Inoue is currently the best pound-for-pound boxer in the world

Naoya Inoue has said he is ready to fight the British boxer Paul Butler “any time and anywhere” in his quest to claim a fourth bantamweight title and become the undisputed world champion.

Inoue made history this month when he beat the Philippines’ 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. The unbeaten Japanese fighter said his sights were now on winning 33-year-old Butler’s WBO belt to complete the collection.
