Paulo Costa warns Chimaev will struggle at light heavyweight

Paulo Costa has issued a pointed warning to Khamzat Chimaev, declaring that a move to light heavyweight would prove "tragic" for the unbeaten contender.

Costa, 35, competes at middleweight where he holds a 16-4 record and sits ranked 13th in the division. The Brazilian out of Team Borracha stands six-foot-one with a 72-inch reach and has built a reputation as one of the most aggressive strikers in the sport, landing 6.26 significant strikes per minute at a 58 percent accuracy rate. He emphasized that he is a natural fit at 205 pounds, describing himself as a "real monster" at that weight and stressing that he does not need to shed muscle mass to compete there.

Chimaev, meanwhile, is the number-one ranked middleweight and sits 10th in the pound-for-pound standings with a 15-1 record. The 32-year-old representing the UAE and Allstars Training Center stands six-foot-two with a 75-inch reach. He is widely regarded as one of the most complete fighters in the sport, combining a 60 percent striking accuracy with a dominant grappling game that produces 5.29 takedowns and 1.8 submission attempts per 15 minutes.

Why it matters

• Costa is positioning himself as a credible light heavyweight threat, suggesting he could pursue opportunities at 205 pounds
• Any move by Chimaev to light heavyweight would immediately shake up the divisional rankings given his current middleweight standing
• The stylistic contrast is stark — Costa's high-volume striking against Chimaev's elite wrestling and submission pressure
• No fight between the two is currently in discussion, making Costa's comments a calculated piece of positioning rather than a formal callout
