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 12 months after the Gunners agreed to pay an initial £27.4m plus £4.2m in add-ons.
Merino was part of the Spain squad who 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 club activating an option to buy him from Brentford following his loan move a year ago.
Merino can operate as a deeper-lying midfielder and it is thought he will complement Declan Rice, who played a ‘box-to-box’ role at times last season.
He also provides Arsenal boss Arteta with another option to compete with Rice, Jorginho, Thomas Partey and Martin Odegaard in midfield.
