Ligue 1 champions Monaco have confirmed the signing of Youri Tielemans on a five-year deal from Anderlecht.
The French giants had been leading the race to secure the youngster’s services and have beaten off competition from Atletico Madrid, Manchester City and Chelsea to land the Belgian.
"Monaco is a club with an ambitious project, recognised on the European stage, and which relies on young players," Tielemans told his new club's website via Sky Sports.
"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."
Monaco 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.
"We are very happy because it proves the increasing attractiveness of our project. His arrival is in line with our strategy of recruiting talented young players.
"This strategy, which allowed us to win the French title and get to the last four in Europe, is bearing fruit."
Tielemans, 20, was a stand out star for Anderlecht in the Europa League this season, with his WhoScored rating (7.35) better than any other player for the Belgian side in the competition.
