Atletico Madrid are reportedly interested in bringing Lorient defender Raphael Guerreiro to the Vicente Calderon this summer.
The Spanish outfit are believed to be close to selling Guilherme Siqueira to Juventus and are targeting another left-sided full-back to provide competition for Filipe Luis.
According to AS, Guerreiro, 21, has been identified as the club's leading target, but they might also face competition from Paris-Saint Germain.
The same report has claimed that Atletico will have to pay in the region of £7m to sign the French-born Portuguese international.
Guerreiro scored seven times for Lorient last season.
