Sagat Petchyindee is whom the street fighter Sagat is based on–like Samart, he is a boxing champion as well as a Muay Thai and Kickboxing world champion. In fact, he taught Firas Zahabi (renown MMA coach of Georges St. Pierre) at a time when Petchyindee did not accept foreigners. Sagat is nothing short of influential and being an ultra winner.
Lawrence Kenshin says so so it must be true lol... i have no idea either to be honestWas Sagat actually an all time great type fighter? I don't know much about him (other than the fact that he coached muay thai legend Firas Zahabi of course).
