Liege had led 1-0 at the break courtesy of M'Baye Leye (14) before two goals from striker Mohammed Tchite (54, 58) put them three to the good.

Mbark Boussoufa pulled one back for the defending champions but late strikes from substitute Erik Bokanga and Mehdi Carcela-Gonzalez sealed a famous win.

AA Gent dropped to fourth after suffering a 3-2 defeat at Club Brugge.

Goals from Dorge Kouemaha (14), Karel Geraerts (26) and Ronald Vargas (28) had put the hosts in total control, and efforts from Yassine El Ghanassy and substitute Bernd Thijs were not enough to salvage a point for Gent.
