Before the World Cup, River Plate placed 24-year-old Paraguayan central midfielder Matías Galarza on the market and intended to use him as a makeweight to acquire players, particularly from Spanish clubs. The club specifically wanted to include him in a deal with Betis, and discussions with that club also involved Lo Celso and the Colombian Deosa. Galarza has 18 caps for his country. He has recently returned from a loan spell at Atlanta United and his contract with River Plate runs until the end of 2028. In addition to Betis, Getafe has also been linked with the player. Transfermarkt estimates his current market value to be €3.00m. In June 2026, Atlanta United had a non-mandatory purchase option valued at approximately €5.6 million for the player's full rights, which was not exercised.
