Percy Tau was involved for Anderlecht, who moved up to third in the Belgian Pro League with a thumping victory over Waasland-Beveren on Saturday evening.
Tau earned his third successive start after having a hand in both goals of Anderlecht's 2-0 win over Cecle Brugge last weekend.
The visitors had a dream start after Adrien Trebel opened the scoring in just the third minute with a strike from close range after he was teed up by Jeremy Doku.
The Bafana forward was central to Anderlecht's second goal in the 18th minute as he setup Lukas Nmecha to have strike one-on-one with goalkeeper Nordin Jackers, who parried the effort away but could not keep out Doku's curler from the rebound.
Vincent Kompany's charges should have went to the break 3-0 up after they were awarded a penalty on the stroke of half-time but Nmecha could not hit the target from 12-yards.
The visitors eventually got the third goal ten minutes from the break after Yari Verschaeren powered home a stunning volley into the top corner at the near post from Doku's through ball over the defence.
Nmecha had a chance to make amends after he won a penalty for Anderlecht on the hour-mark and he went up himself to make it 4-0 with a powerful strike past Jackers.
Beveren pulled a goal back four minutes later from a quick counter-attack after Din Sula tapped into a gaping net a square pass from Joseph Isiah.
Daan Heymans pulled the second goal back for the hosts in the last two minutes but it was too little too late as Kompany's men kept their unbeaten streak to go up to third, six points behind surprise leaders Charleroi.
