Cesar Azpilicueta has bid farewell to Chelsea after 11 years.
The Spaniard has left the Premier League side by mutual consent with one year remaining on his contract.
ESPN reports that Atletico Madrid are closing in on a deal to sign the defender on a free transfer.
“Cesar leaves an everlasting mark at Chelsea, as a warrior, as a champion, and as loyal Chelsea legend,” Todd Boehly, Chelsea chairman, and Behdad Eghbali, co-controlling owner, told the club’s website.
“He has set the standards at the club for more than a decade and demonstrated to everyone what is required day in, day out to achieve success.
“Coaches and teammates past and present have trusted him to lead by example as captain. He has done so immaculately on and off the pitch, something for which we are grateful. For that and so much more, Cesar will always be welcomed back at Stamford Bridge.”
