Thierno Ballo is considering a transfer this summer. Among the clubs showing interest is Glasgow Rangers, who are set to participate in the second qualifying round of the Champions League. Ballo's market value stands at 5 million euros, and a transfer fee slightly exceeding this amount would set a new record for the most expensive departure in Wolfsberger AC's history. Besides Rangers, both Mainz 05 and Ajax Amsterdam are keeping an eye on the 23-year-old offensive player. Mainz has secured a spot in the Conference League, while Ajax will compete in the Europa League, but a potential move to Rangers could provide Ballo with the chance to play in the Champions League. Although the exact transfer fee being sought by Wolfsberger AC remains undisclosed, any fee exceeding 5 million euros would make Ballo the club's most profitable sale, overtaking the previous record held by Mohamed Bamba.
