The 2020–21 Belgian National Division 1 was the fifth season of the third-tier football league in Belgium and the first under its new name after changing from First Amateur Division to National Division 1. Eventually, the season was cancelled in January 2021 with just a few matches played, as measures taken by the Belgian government against the spread of COVID-19 prohibited amateur football.[1]
Just before the season started, Roeselare went bankrupt. Initially, it seemed as though a third-party would be willing to take over the club, with Roeselare forfeiting its first two matches while negotiations continued, eventually however the club folded and the league was to be played with only 15 teams. All results were removed and Roeselare ended in last place.
Due to the COVID-19 pandemic, the league had started later than initially planned, with the first matches played only in September. Mid-October, with only the first four matchdays partially completed, the league was stopped as the second wave of the COVID-19 cases was in full force. With amateur football allowed again as from February 2021, it was decided in early December 2020 to restart the amateur leagues from mid-February 2021, in case the pandemic has evolved positively. Any matches from the first four matchdays which still need to be played can be played already from the beginning of February. In any case, the 2020–21 season was shortened, consisting of only the first half of the season, meaning a single round-robin tournament in which all teams play each other just once. All direct promotion and relegation places were to remain valid, but all post-season playoff tournaments were canceled, with no extra promotion and relegation rounds taking place, which meant that:
With the planned restarting date coming closer, but COVID-19 figures still high, on 12 January 2021 a first meeting was held between representatives of both the Flemish and Francophone amateur football; the Belgian FA; the union of professional football clubs; and politicians, on whether to cancel the season entirely. The representatives concluded to postpone the decision to 25 January 2021, taking into account the result of the COVID-19 consultation committee of 22 January in which the possibility of relaxing the lockdown measures would be decided.[3] Eventually, the decision was taken to cancel the season entirely.[1] As a result, no teams were promoted or relegated from the league.
