Mundo Deportivo reports on the potential transfer of 23-year-old Spanish defender Arnau Martínez to Espanyol. Martínez of Girona, which he joined in April 2021, has been linked with Espanyol, who are seeking a left-back. Martínez, whose natural position is right-back, is reportedly among a number of full-backs being considered by the club, including Diego Rico of Getafe, Angeliño of Roma, and his Girona teammate Álex Moreno. In the 2025/2026 LaLiga season, Martínez made 35 appearances, scoring 2 goals and providing 3 assists. The Spain U21 international, with 12 caps, has also been linked with several other clubs including Lazio, Fiorentina, and Real Betis. Following Girona's relegation, reports from June 2026 state that the player's release clause has decreased to between €7.5 million and €8 million. His current Transfermarkt market value is €10.00m.
