Cristian Rodriguez and Jose Gimenez have been strongly linked with moves away from Atletico Madrid.
AS reports that Cebolla wants to quit Vicente Calderon despite being happy at the club in every aspect bar the amount of playing time he got last season.
Sunderland are said to be interested in the Uruguay international and Atletico are looking for a replacement, which would hurry Rodriguez out of the club.
The Black Cats are also said to be interested in Gimenez, as are Benfica and a host of clubs in La Liga.
Deportivo La Coruna, Villarreal, Rayo Vallecano and Malaga are also in the hunt but Atletico don’t want to let the defender go.
Atletico are said to be concerned about the numbers available in defence if Gimenez was to leave, although Emilio Insua and Javi Manquillo can go, the latter on loan to Liverpool.
