Israel Adesanya v. Paulo Costa (UFC 253, September 27): Dana White predicts this middleweight title clash will be fight of the year, and it’s not difficult to see why. Both champion and challenger are undefeated – Adesanya 19-0, Costa 13-0 – and there’s genuine animosity between them. Making his second title defence, Adesanya is one of the sport’s most technically gifted athletes, hence “The Last Stylebender” moniker, while Costa is a wrecking ball of a fighter. Perhaps crucially, Adesanya is out to prove March’s lacklustre victory against Yoel Romero was simply an aberration on an otherwise glittering CV, and what better way than dominating a guy who’s only once in 13 bouts been pushed to three rounds. Can Costa’s cardio keep up? Nevertheless, fireworks are expected. Courtesy Zuffa LLCCourtesy UFC
