Kell Brook has his sights set on another world title tilt after marking his light-middleweight debut with a stunning second-round knockout of Sergey Rabchenko at the Sheffield Arena.

Kell Brook dismantled English rival Frankie Gavin in six rounds to retain his IBF title and turn his attention to making a serious dent in the welterweight division.

Floyd Mayweather Sr believes it is only once his son has retired that his genius will be truly appreciated.

Kell Brook has called Amir Khan’s bluff regarding a potential grudge fight between the pair – telling his British rival: “It’s not about money for me.”
