Ibrahima Diaby, a 19-year-old French and Guinean defensive midfielder, has joined Al-Ahli from Cercle Brugge for a transfer fee of approximately €10 million. This amount could increase with €3.5 million in add-ons that are not all considered easy to achieve. Celtic had also attempted to sign Diaby during the summer, but their bid of over €8 million was rejected. Diaby joined the Belgian club in July 2025 and, according to Transfermarkt, has a current market value of €1.50m.
