Championship play-offs
The points obtained during the regular season were halved (and rounded up) before the start of the playoff. As a result, the teams started with the following points before the playoff: Genk 32 points, Club Brugge 28, Standard Liège 27, Anderlecht 26, Gent 25 and Antwerp 25. The points of Genk, Standard Liège, Anderlecht and Antwerp were rounded up, therefore in case of any ties on points at the end of the playoffs, the half point will be deducted for these teams.
