Madrid - Brazilian defender Filipe Luis is returning to Atletico Madrid just a year after they sold him to Chelsea, the clubs said on Tuesday.
Atletico sold the long-haired 29-year-old to the London side for a reported €22 million a year ago after they won the Spanish league in the 2013/14 season.
Now the Brazil international has signed up to return to Atletico for four seasons, the club said in a statement.
British media reported that Atletico paid about €15 million to buy him back.
Luis won the Premier League with Chelsea and scored in their League Cup final victory but only played 26 games overall under coach Jose Mourinho.
"Happy! Glad to be coming home and to be a new Atleti player," Luis said in a Twitter message.
Atletico's sporting director, Jose Luis Perez, called Luis "one of the most talented wingers in the world".
"He already knows our club and our way of playing so he will adapt quickly," Perez said.
A statement on Chelsea's official website announced simply: "We wish him all the best for the future."
