Samet Agdeve isn't just confident heading into his promotional debut - he's downright frightening, even to himself.The 21-year-old undefeated Turkish slugger (17-0) faces reigning double champ Roman Kryklia for the inaugural ONE heavyweight kickboxing world title at ONE Fight Night 37 in Bangkok, Thailand, this Friday, November 7.In a pre-fight interview with ONE Championship before he battles the ONE light heavyweight kickboxing and heavyweight Muay Thai world champion, the promotional newcomer unleashed a chilling assessment of his own capabilities and predicted exactly how he'll finish the Ukrainian powerhouse."I'm a fearless fighter. Sometimes, I'm even a little scared of myself," Samet Agdeve said, before sharing his take on how this massive world title fight ends."I'll knock [Kryklia] out not with a high kick, but with a high punch. He doesn't have much of a chance against me. My only slogan is: kill or be killed."Agdeve, after all, has put 12 opponents to sleep throughout his career with a variety of match-ending weapons. By the looks of it, he's fired up to add another huge name to his list of victims at ONE Fight Night 37.
