Anderlecht general director Herman van Holsbeeck has suggested that the club will announce the sale of Youri Tielemans to AS Monaco in the coming days.
Everton and Manchester City have previously been linked with the 20-year-old, who has already scored 29 goals in 171 appearances in all competitions.
However, it appears that he has turned down an opportunity to move to the Premier League, with Champions League semi-finalists Monaco ready to secure his signature.
Van Holsbeeck told VTM: "Youri Tielemans will be leaving Anderlecht. We will make an announcement about him in the upcoming week.
"There are still a few details that need ironed out, but Youri will normally leave the club before the end of the week. His move to Monaco is not 100% done yet, but they are the club that has shown they are very eager to sign Youri."
Tielemans has also earned three caps for the Belgium national team.
