Monaco have signed Lucas Ocampos on a six-year contract for an undisclosed fee believed to be in the region of 16 million euros.
The principality club spent last season in Ligue 2, and although they failed in their attempt to regain their top-flight status at the first attempt, they have recently secured big-money backing from Dmitry Rybolovlev.
And they have wasted no time in spending a sizeable fee on the 18-year-old, who has won eight caps for Argentina at under-17 level, signing the teenager from River Plate.
“Monaco are delighted and proud to announce the formalisation of the transfer of Lucas Ocampos from River Plate,” a statement on the club’s website read.
“The young 18-year-old Argentine has signed a six-year contract with the club, and will be presented to the media on August 17.”
Monaco got their Ligue 2 campaign off to the perfect start with a 4-0 win over Tours on July 30, but could only manage a 0-0 draw with Stade Lavallois a week later.
Friday’s win over Istres leaves them in second spot.
Andrea Raggi, Jakob Poulsen, Delvin N’Dinga and Emir Bajrami also moved to Stade Louis II during the transfer window, while Claudio Ranieri joined as coach.
