The Spanish centre-back has joined the Catalan club on a two-year deal with a €400m release clause that will see him stay at the Camp Nou until June 30, 2025. The 32-year-old was a long-term target for Barcelona and is an experienced campaigner who appeared in over 350 La Liga games with Athletic, scoring 22 goals.
Martinez had been in talks with the La Liga champions since January and after his contract with Athletic ended in June, he signed on the dotted line for Barcelona having reached a verbal agreement in April. He had already completed his medical last month and was spotted at the club's training facilities on Tuesday while doing a photo session for his unveiling.
Martinez beccomes the second signing for Barcelona this summer after they roped in treble-winner Ilkay Gundogan from Manchester City, who was also a free agent. Both players will be available for pre-season training in July before heading off to the USA tour where the club will face the likes of Juventus, Arsenal, Real Madrid and AC Milan.
