Chelsea are reportedly in talks to sell Felipe Luis to Atletico Madrid, according to the Le10 Sport website.
The 29-year old left back starred for Atletico during the 2013-14 season, in which they won the La Liga title and also reached the UEFA Champions League final.
His starring role, however, prompted a move to Chelsea and he joined the Blues last summer.
However, it has not worked out fine so far and he has found himself on the bench more often than not.
And reports says Luis would only prefer to return to Atletico, with boss Diego Simeone also keen on a reunion.
