Racing Club de Lens, usually known as RC Lens or simply Lens, was established in 1906 under rather humble circumstances. The club traces its beginnings back to a group of high school students who banded together to create a football team that would compete against other local youth sides (source).
The early years for the Blood and Gold were not filled with immediate triumphs. Instead, the young team found itself grappling with financial instability while trying to establish its identity on the pitch. However, this period also saw the emergence of several notable players who contributed significantly towards stabilizing and eventually elevating RC Lens' stature in French football.
One such player was Stefan Dembicki, a Polish immigrant who became one of RC Lens’ first stars during his tenure from 1934-1948 (source). His goal-scoring prowess helped bring regional recognition to the club and attract more talent.
