Besiktas have sent scouts to Brazil to monitor the Palmeiras midfielder Marcos Arouca.
The Istanbul based club are on the hunt for a new central midfielder after failing to agree terms with Atiba Hutchinson.
Atiba’s contract with Besiktas expires at the end of the season and the 32-year-old is expected to sign for Toronto FC in July.
Arouca has three years remaining on his contract but can leave for a cut price if a European side wants to sign him due to a clause in his contract.
The 28-year-old made 32 appearances for Palmeiras during the 2013-14 season.
Beşiktaş are currently first in the Süper Lig but just one point separates them from second placed Galatasaray and third placed Fenerbahçe.
The Black Eagles take on Trabzonspor this weekend at the Hüseyin Avni Aker Stadium.
