The France international appears set to move to La Liga following three seasons with the principality club
Atletico Madrid have announced an agreement has been reached to sign Monaco star Thomas Lemar for a reported fee of €60 million (£52.9m/$70.5m).
The 22-year-old France international has been subject of interest from Arsenal and Liverpool among others, but he now appears destined for a move to La Liga.
The Guadeloupe-born attacker joined Monaco from Caen ahead of the 2015-16 season, and eventually established himself as one of Ligue 1's best left-sided players.
Lemar broke through in the 2016-17 campaign, scoring 14 goals and adding 17 assists as Monaco won Ligue 1 and reached the Champions League semi-finals.
The France international could now be set to join up with his international team-mate Antoine Griezmann with the Rojiblancos — if the 27-year-old decides to stay put.
On Tuesday Griezmann revealed he has made a decision regarding a potential summer transfer to Barcelona, but isn't ready to make that decision public.
Griezmann has called on Atletico to invest more in their squad, and Lemar's arrival is a sign the La Liga runners-up are taking their star's advice.
Lemar and Griezmann are a part of the France team that will begin their Group C campaign against Australia on Saturday, before facing Peru and Denmark in the group stage.
