Matías Galarza, a 24-year-old Paraguayan midfielder, has returned to River Plate following a loan at Atlanta United FC in MLS. Sunderland is one of several teams that have shown interest in him. Olympiacos, Getafe, Monza, and Strasbourg are also interested parties. The Greek and Spanish clubs are currently pursuing him most strongly. Following his performances at the World Cup, River Plate is expected to increase its valuation of the player. His valuation was previously between €4.5 and €5 million. In June 2026, Atlanta United had a non-mandatory purchase option valued at approximately €5.6 million, which was not exercised. Galarza has 18 caps and 4 goals for Paraguay and made 10 league appearances during his recent loan spell.
