Atletico Madrid are tracking Velez Sarsfield midfielder Santiago Cáseres.
AS says Atletico chief Andrea Berta is in Argentina this week and has made a personal scouting check on Caseres.
Berta saw the 21 year-old in action for Velez's 2-2 draw with San Lorenzo.
Atletico are set to bring Rodri back to the club from Villarreal this summer, but remain in the market for another midfield signing.
And Caseres is under consideration, with Berta dispatched to Argentina specifically to check on the midfielder personally.
