Hamburg SV and Celtic FC are currently engaged in discussions regarding the 23-year-old Tunisian international winger Sebastian Tounekti, who is the German club's top target for the winter transfer window. Hamburg SV made an initial offer estimated at 11 million euros, which was quickly refused by the Scottish club. A second proposal of around 13 million euros was also rejected. Celtic does not want to part with Sebastian Tounekti, who was signed on the last day of the summer transfer window from Hammarby IF for an estimated 6.4 million euros. At this stage, Celtic is maintaining its position and does not appear willing to allow a departure this winter, with the player's contract not expiring until 2030. Hamburg is considering its next steps as the end of the transfer window approaches.
