Alvarez vs. Golovkin has been in the cards for more than a year. Last May, after Alvarez comfortably dismantled Amir Khan, he vacated his WBC middleweight title after he was unable to strike a deal to face Golovkin, who was the mandatory challenger. Golovkin is currently the WBA (Super), WBC, IBF, and IBO middleweight champion of the world, and is generally near the very top of pound-for-pound lists.
