## Background

Eersel was born in Paramaribo, Suriname and moved to the Netherlands with his family when he was four years old. He started taekwondo at the age of eight, and transitioned to rugby afterwards. At the age of 15, he started training at Sityodtong Gym in Amsterdam. His nickname, The Immortal, was given to Eersel in this early amateur era. His teammates gave it to him, as he never used the break time between the rounds to sit and regain breath.
As it was not easy to find competitors in the Netherlands after becoming a professional athlete in his weightclass, he tried his luck abroad. In Baku, Azerbaijan, Eersel took part in a K1-tournament, where he qualified for the finals. He did not win the finals, but the hunger for more had started.
After this Eersel was invited for competitions in his country of birth Surinam, Russia (W5), Greece, Germany, Turkey (Mix Fight Gala), the US (Legacy and Lion Fight) and China (Wu Lin Feng, Glory of Heroes).
