Numsurin Chor Ketwina believes that he is a heavy underdog against Nadaka in their scheduled title clash next month in Japan. He, however, is embracing the tag, determined to use it in getting a big victory on fight night.The two strikers are to dispute the inaugural ONE atomweight Muay Thai world title at ONE 173: Superbon vs. Noiri on Nov. 16 at the Ariake Arena in Tokyo. It is one of seven world title matches featured in ONE Championship's second live on-ground event in the 'Land of the Rising Sun' this year.In an interview with ONE, Numsurin shared his thoughts on his world title clash against hometown bet and fan favorite Nadaka, highlighting that most of the pressure is on his opponent and that he looks to tap it in his favor.The 30-year-old Thai star said:"There’s no pressure for me because I am the big underdog. I am chill but deep down, I hope that I will get the belt. ONE’s Muay Thai belt is globally renowned. If I get it, I will be more famous. And if I get to beat someone who has never lost. I’ll try my best."
