Chelsea have reportedly reached an agreement with Atletico Madrid to sell full-back Filipe Luis for around £15m.
The 29-year-old has failed to settle at Stamford Bridge since joining from the Rojiblancos last summer.
Luis could now be on his way back to the Spanish capital, with Sky Sports News suggesting that a deal between the two clubs has been struck.
Earlier reports claimed that a transfer worth £11m could be on the table, which largely hinged on Atletico first offloading Guilherme Siqueira, but a switch is now thought to be close to completion.
Luis spent four years at the Vicente Calderon during his first stint at the club.
