Real Sociedad has started to make moves in the summer market to assemble the squad for the next season. The club's director of football, Erik Bretos, has added two new names to his agenda of objectives. The Argentine defender Lautaro Rivero, from River Plate, and the winger Joaquín Martínez Gauna, known as Oso, who currently plays for Sevilla, are the two new candidates. The interest in Lautaro Rivero responds to the need to incorporate a left-footed central defender with projection after the latest movements in the Real Sociedad's backline. At 22 years old and 1.85 meters tall, the Argentine defender stands out for his solidity and ball exit, qualities that have also caught the attention of Udinese and a Mexican league club. The first information from Argentina suggests that River Plate's economic demands to release the player are around 10 million euros. The other alternative to strengthen the left-back position is Oso, a player who is very popular among Zubieta's coaches for his versatility and range, according to AS. The 22-year-old player has been one of the positive notes of the season in Sevilla, a performance that has put him on the radar of the Argentine national team's coach, Lionel Scaloni, for a future call-up. The club of Nervión considers his continuity a priority and is actively working on extending his contract, a matter where there is optimism in the offices of the Ramón Sánchez-Pizjuán, although there is no closed agreement yet.
