Martin has signed a contract extension with Real Sociedad through the end of the 2031/32 season, according to the club.
Analysis:Martin has become a regular fixture in the back line at just 20 years old, establishing himself as a key piece of Real Sociedad's defense since breaking into the first team. The new deal reflects the club's confidence in the center back's development, with plenty more expected from him as he continues to build on his early impact at the top level. During the 2025/26 season, he contributed two goals, 31 tackles, 34 interceptions and an impressive 159 clearances in 25 starts and will look to build on that campaign heading into 2026/27.
