Barcelona have reportedly asked Monaco how much it would cost to sign Thomas Lemar.
Sky Sport's Gianluca Di Marzio previously reported Atleti had opened negotiations with Monaco over the 22-year-old (via Get French Football News):
Lemar emerged as a top-class talent in 2016-17. He played a key role in Monaco's Ligue 1 title win and their run to that season's UEFA Champions League semi-finals.
He remained at the Stade Louis II, and although neither he nor Monaco enjoyed quite as good a campaign in 2017-18 as the previous season, he is still widely regarded as one of the top young attackers in Europe.
Lemar is part of Didier Deschamps' Les Bleus squad for the FIFA World Cup in Russia this summer.
That could delay negotiations for any move, but it should also give Barca the time to lay the groundwork for an approach.
The Blaugrana squad is already awash with attacking talent. In the past year alone, the Camp Nou giants have spent more than £200 million on Ousmane Dembele and Philippe Coutinho.
Lemar is young and still has a number of years until he hits his peak.
He is versatile enough to operate in a number of attacking positions and deeper in midfield if need be, so he could be a fine long-term addition to the Barca squad.
