Atletico Madrid have re-signed Tiago Mendes on a two-year deal, despite leaving the club this summer.
The midfielder left Vicente Calderon at the end of their title-winning campaign, after his current contract expired.
However, despite talks with Chelsea, the 33-year-old has opted to go back to Los Colchoneros, and has put pen to paper on a two-year deal.
“The club offered me the possibility of a renewal. I felt proud because we’d had an incredible season, but I thought it was time to close a cycle,” he told their official website.
“I had the opportunity to play in various international Leagues and I took some time to assess the various options during the summer, but at the time of taking the final decision, it was clear to me that Atleti was the only right choice.
“During these weeks many false things have been said about me, but that doesn’t change anything. Since the season ended, I had not completely forgotten Atleti nor had the club completely forgotten about me.
“Cholo always left the door open for me and now I'm very happy because I know that I’ve made the right choice.
“I want to thank the club very much for waiting for me and for offering me the opportunity to stay here. I look forward to helping the team in everything I can.”
