Cesc Fabregas is being linked with a potential move to Atletico.
The Chelsea man is currently in an out of Antonio Conte's side and Eurosport report he could be in line for a sensational return to Spain.
However, it depends on Atletico successfully overcoming a transfer ban which currently prohibits them from signing players this summer.
Real Madrid have received news that they are allowed to sign players this summer and the Rojiblanco are hopeful the CAS will allow them to make moves in the market, too.
Eurosport believes that Atletico think Fabregas could have the same success David Villa had at the club - the former Spain forward helped them win the league in his one season at the Calderon after joining from Barcelona.
