ONE Championship CEO Chatri Sityodtong thinks Angela Lee could be making a serious mistake as she pursues women’s MMA history next month at ONE Championship 83.

Lee (9-0), the organization’s current atomweight champion, will attempt to become the first simultaneous two-division titleholder in women’s MMA history when she challenges women’s strawweight champ Jing Nan Xiong (13-1) in a headlining contest.

Although Lee is unbeaten and has been successful in her own weight class, she’s opted to move up a weight class for the bout with Xiong. From Sityodtong’s perspective, that might not be the wisest choice.

“I actually don’t know why Angela is doing this moving up to fight a bigger, stronger, faster champion,” Sityodtong told reporters, including MMAjunkie on a recent ONE Championship 83 media call. “This could be Angela’s first potential loss. This is a high-stakes game. This is a world champion verse world champion fight.”

ONE Championship 83 takes place Nov. 9 at Singapore Indoor Stadium in Singapore. The entire card streams on the ONE Championship app.

Sityodtong made it clear he’s not trying to play favorites when analyzing the fight; he simply is calling it how he sees it. Most of the scenarios throughout MMA history where a fighter tries to go for two belts sees the smaller athlete going up in weight, and the results have been mixed.

“I put Angela as a heavy underdog in this fight because she’s moving up a weight against a very, very dangerous KO striker with a 13-1 record,” Sityodtong said. “She’s finished almost everybody she’s faced. That being said, I also know Angela and she’s always about making history.”

Lee is always about making history, and she’s no stranger to it thus far. Her first ONE Championship belt came at just 19, and since then “Unstoppable” has gone on to defend it multiple times.

Is Lee biting off more than she can chew this time around, though? Sityodtong seems to feel that way, but also said Lee can never be counted out.

“At 19 years old she became the youngest world champion in the history of any major organization globally,” Sityodtong said. “She’s going to try to make history again as a two-division world champion. She’s not one to shy away from challenges, but let it be very clear: She’s going against a more experienced opponent, a heavier opponent, a stronger opponent who has more KO power. I think Angela’s risking it all on this fight.”
