Anderlecht's title success

The battle for the title was not great as Anderlecht had a big lead over their opponents (mainly Club Brugge). However, a bad finish from Anderlecht kept the suspense until the 31st matchday when Club Brugge drew with Mouscron while the team from Brussels also drew (1-1) at Herman Vanderpoortenstadion, the homeground of Lierse.

Battle for Europe

The next week, Club Brugge was sure to enter the UEFA Champions League Preliminary Round with a 1-0 win against Standard Liège, then lying third. In spite of this defeat, Standard managed to qualify for the UEFA Cup as they were 6 points ahead of Mouscron after the 32nd matchday. The suspense was killed after a 1-1 draw against Charleroi the next Saturday.

The relegation dog fight

The end of the league was thus centered on the battle against relegation. Four teams were concerned : R.A.E.C. Mons and Charleroi, which finally saved themselves, R. Antwerp F.C. and K. Beringen-Heusden-Zolder finishing respectively 6 and 5 points adrift.
