Versatile defender Azpilicueta has one year left on his Chelsea contract but sources have told ESPN that the Premier League side won’t block his departure as a free agent as Atletico continue to strengthen their back line after the arrival of left-back Galan.
Atletico have spent €3.5 million ($3.82m) for Galan, who has penned a deal until 2026, in addition to allowing full-back Manu Sanchez move the other way as part of the operation.
Atletico are also set to sign defenders Caglar Soyuncu, whose contract with Leicester City has expired, and Santiago Mourino from Racing Club de Montevideo.
Atletico coach Diego Simeone has previously tried to sign Azpilicueta, who turns 34 in August, and has now finally managed to bring him to the club.
In 11 seasons at Stamford Bridge, he has made 508 appearances, including 32 last season, helping the club win the Champions League in 2021.
Inter Milan also tried to sign Azpilicueta this summer but once Atletico learned a deal was possible they worked quickly to finalise the signing.
The player’s desire to return to his homeland also played a role in his decision to join Atletico, who will look to challenge Barca and Real Madrid for the title next season after finishing third this past campaign.
