Coming off the biggest win of his 32-fight professional career , David Benavidez has his sights locked on one particular matchup. Benavidez's flawless win over Gilberto 'Zurdo' Ramirez makes him a two-division champion, owning the WBA and WBO cruiserweight titles along with the WBC and WBA light heavyweight belts. As impressive as he was in his 200-pound debut, the 29-year-old wants to go back to his natural weight class to settle an old score. "We're going after Dmitry Bivol," Benavidez said on 'The Ariel Helwani Show.' "I told you guys that's what I wanted to do. Just for the fans to have something to look forward to, that's why I give you guys my breakdowns of my plans. I told you guys I'm gonna come back down and fight Bivol; that's exactly what I'm gonna do. I've won two more titles at cruiserweight. Now it's time to capture the rest at light heavyweight." David Benavidez wants Bivol next. #HelwaniShow pic.twitter.com/BtpAd6gNwx — Jed I.…
