Arsenal have completed the signing of Spain midfielder Mikel Merino from Real Sociedad for a fee that could reach £31.6m.
The 28-year-old moves to north London on a four-year contract with the option of a further year after the Gunners agreed to pay an initial £27.4m plus £4.2m in add-ons.
Merino was part of the Spain squad that won Euro 2024, featuring in all seven matches in the tournament and scoring a late winner in extra time against Germany in the quarter-final.
He becomes Arsenal's third signing of the transfer window, after the arrival of Italy defender Riccardo Calafiori and Spain goalkeeper David Raya, with the Gunners activating the option to permanently buy him from Brentford.
