Midfielder Mikel Merino has completed his move to Arsenal from Real Sociedad in a deal understood to be worth €32.5 million ($36.3m), the north London club announced on Tuesday.
The 28-year-old was part of the Spain team that lifted the Euro 2024 title, contributing most notably with an extra-time winner against Germany in the quarterfinals.
Real Sociedad coach Imanol Alguacil left Merino out of the squad for their LaLiga opener against Rayo Vallecano due to talks advancing with Arsenal at the time of the match, and he also did not feature in the team's win over Espanyol last weekend.
