Boxing star Jermall Charlo is an undefeated champion, but says if he wants to be remembered as an immortal fighter, he needs to fight and KNOCK OUT Canelo Alvarez.
The 30-year-old WBC middleweight champ (30-0, 22 KO's) is fighting Sergiy Derevyanchenko Saturday night on Showtime. Derevyanchenko -- a former amateur champ -- has only lost 2 pro bouts and gave Gennady Golovkin a tough fight.
Beating Sergiy would be a good win ... but Charlo tells TMZ Sports if he wants to be remembered as one of the greatest ever, he needs to go big game hunting.
