Monaco have signed winger Jordi Mboula on a five-year deal from Barcelona.
The 18-year-old, who has featured for Spain's age-group sides, garnered attention earlier this season following a stunning solo goal in a UEFA Youth League game against Borussia Dortmund.
Mboula, a product of the Barcelona academy, had been expected to sign a new deal at the Camp Nou, but will instead head to the Stade Louis II.
Monaco vice-president Vadim Vasilyev told the club website: "Jordi Mboula has shown very good things with the youth team of FC Barcelona and AS Monaco offers him an ideal environment to continue his progress.
"As we have done with players such as Bernardo Silva, Fabinho and Tiemoue Bakayoko, we will support him and help him grow in our team. "
Monaco have already signed Belgian international midfielder Youri Tielemans from Anderlecht, defender Jordy Gaspar from Lyon, Swiss international goalkeeper Diego Benaglio from Wolfsburg and midfielder Soualiho Meite from Belgian side Zulte Waregem.
