Martinez joined Barcelona in 2023 from Athletic Club on a free transfer, signing a two-year deal. His early days were disrupted by a foot injury, but he soon established himself as a reliable presence in the defence during the 2024–25 season.
Amid his own challenges, Martinez found a connection with one of Barca’s youngest talents, Yamal. The two shared the pitch during the treble-winning season, including La Liga, Copa del Rey, and Supercopa de Espana victories. Yamal, then just 17, looked up to Martinez as a guide and role model in a demanding locker room. The 34-year-old Spanish centre-back shares the pressures faced by the teenage star carrying the hopes of a club still rebuilding its identity.
