Alvarez, after his win over Amir Khan in May and with Golovkin in the ring, said they would fight. Well, Alvarez made a U-turn and agreed to fight Golovkin next September.

Golovkin wants to fight top contenders and hold all the titles at 160 pounds, so he tried to make a fight with WBO middleweight champ Billie Joe Saunders. Saunders either priced himself out of the bout or — like other boxers Golovkin wanted to face — got scared and didn’t want to fight. Golovkin then turned to Chris Eubank Jr.; the same thing happened.

Eubank manager Eddie Hearn called Tom Loeffler, who represents Golovkin, and proposed another fighter, IBF welterweight champion Kell Brook. Negotiations went smoothly and the fight was made for Saturday at the sold-out O2 Arena in London. Golovkin, known as “GGG,” will defend his WBC, IBF and IBO middleweight titles against Brook.

Brook (36-0, 25 KOs) will look to become only the third reigning welterweight titleholder to move up and win a middleweight world title. The other two were the legendary Sugar Ray Robinson and Carmen Basilio.

Golovkin (35-0, 32 KO’s) will be looking to make his 18th consecutive title defense and 23rd consecutive knockout.

Expect fireworks and fight of the year potential. These are the world’s most dangerous boxers, men no one wants to face.
