Real Sociedad is looking for versatile defenders who can also play in wider positions, and 23-year-old Spanish full-back Arnau Martínez is a player with these characteristics. Following Girona's relegation, the player's release clause has dropped to 8 million euros. According to a statement by Matteo Moretto on Radio Marca, there is interest in Martínez from a LaLiga club that competes in Europe, and Moretto reportedly smiled when Real Sociedad was mentioned. In the 2025/2026 LaLiga season, Martínez made 35 appearances, scoring 2 goals and providing 3 assists. The defender has also been linked with clubs including Lazio and West Ham United. Previously, Girona's asking price was reported to be around €15 million, with various reports in 2025 and early 2026 mentioning a release clause of €14 million. Martínez, who has 12 caps for Spain's U21 team, has a current market value of €10.00m, according to Transfermarkt.
