UFC middleweight champion Robert Whittaker and interim champ Israel Adesanya will unify the 185-pound gold inside the Octagon.
While Michael Bisping held out for a fight against Georges St-Pierre, Whittaker beat Yoel Romero in a five-round slugfest on a battered leg to win the interim title.
At UFC 236, while Whittaker was recovering, Adesanya bested Kelvin Gastelum for the interim gold in what could be 2019's Fight of the Year.
Not only are these two the best middleweights, but they are the best middleweight strikers with distinctive styles and a willingness to stay in the pocket and exchange.
Conventional wisdom will say Adesanya has a decided advantage on the feet, but the Gastelum fight proved he is not invincible.
