Dieselnoi Chor Thanasukarn is arguably the GOAT. He definitively beat Samart, widely regarded as the GOAT, in the Fight of the Year, and eventually just ran out of opponents just as Muay Thai was peaking in talent. This portrait is of his knee, the greatest knee in history, though many will tell you that his Muay was much more than knees, or height.
In Thailand the land and the soul are woven in the work.
