Atletico Madrid are considering a move for Napoli midfielder Allan, according to reports in Italy.
Diego Simeone has already spent over €200m on new players this summer following the big money departures of Antoine Griezmann, Lucas Hernandez and Rodrigo Hernandez.
The Argentinean boss has brought in Marcos Llorente and Hector Herrera to stiffen up his midfield options, however according to reports in Tuttosport he is also interested in the 28-year old Brazilian.
Allan has established himself as a key figure during four Serie A seasons at the Stadio San Paolo, and manager Carlo Ancelotti is not keen to let the former Udinese defensive midfielder leave.
According to the report, Atletico are set to test Napoli's resolve in the coming days with a €55m bid.
Both clubs reportedly remain interested in Real Madrid's James Rodriguez, however neither are willing to match Los Blancos €45m asking price for the Colombian international.
