Manchester United target Youri Tielemans has left Anderlecht to join Monaco.
The 20-year-old signed a five-year contract with the French giants hence ending speculation about a possible move to the English Premier League.
He was also a target for rivals Manchester City.
"Monaco is a club with an ambitious project, recognised on the European stage, and which relies on young players," he told the club's official website.
"I am very happy to be here.
"I will now do everything possible to progress here and repay the confidence the club have shown in me."
Vice-president Vadim Vasilyev added: "Youri won the Belgian championship and was voted the best player.
"He was courted by very big clubs but it is Monaco with whom he chose to make progress."
