Valentin Rosier, currently playing as a right-back for Leganés, has attracted interest from Osasuna. He is seen as an ideal replacement if Jesús Areso departs. Rosier's contract with Leganés ends on June 30, making him an appealing target. Osasuna faces competition from clubs with greater economic strength, notably Fulham and Eintracht Frankfurt, who are also keen on the 28-year-old French defender. Rosier, who joined Leganés as a free agent from Besiktas last summer, has been a standout performer this season, playing 82 percent of the league minutes under manager Borja Jiménez.
