Real Sociedad has been following River Plate defender Lautaro Rivero. Contacts began to be established two months ago, according to AS.

The club is exploring options such as retaining a percentage of future sales and capital gains. Rivero has a release clause of 100 million.

Real Sociedad is closely following Lautaro Rivero, a 22-year-old Argentinian defender from River Plate. The club has reportedly made a formal offer to acquire him, although this is not fully confirmed in Donostia. Rivero is a left-footed player and is considered to fit the profile for a central defender sought by the coaching staff led by Pellegrino Matarazzo. Real Sociedad's interest is also due to Rivero's recent call-up to the Argentina national team by Lionel Scaloni and his defensive versatility, as he can also play as a left-back. Rivero is currently one of several options on a list held by the club's sporting director, Erik Bretos. The defender joined River Plate in January 2024, has a contract until the end of 2029, and has one cap for his country. He made 14 appearances and scored one goal in the 2025/2026 Torneo Apertura. Several Serie A clubs, including Roma, Inter, and Lazio, have also been linked with the player. His market value is estimated by Transfermarkt to be €7.00m. According to reports from May 2026, Roma is considering an offer between €15 million and €20 million. Another report from May 2026 suggested a purchase price of around €10 million. It was previously reported in February 2026 that River Plate expected a sale for more than €30 million.
