Frank Acheampong climbed off the bench to score the second goal as Anderlecht beat Sporting Charleroi 2-0 on Boxing Day in the Belgian top-flight.
The Ghana international replaced Massimo Bruno on 59 minutes when the scoreline was still goalless.
Lukasz Teodorczyk opened the scoring on 74 minutes and Acheampong grabbed the assurance goal with five minutes left on the clock.
He collected a pass from the right, controlled well inside the box before shooting in at the near post.
It was his second league goal in 17 appearances this season as the Jupiler League goes on a break.
