Ermin Mahmić

In August 2026, reports indicated Slovan Liberec's asking price was between €7 million and €8 million, with other reports citing a similar range of £6-7 million (approx. €7.1-8.3 million) amid interest from Celtic. In June and July 2026, it was widely reported that the club was demanding a fee of more than €10 million from interested German clubs like RB Leipzig, FC Köln, and Eintracht Frankfurt. During this period, his Transfermarkt value was consistently cited as €5.00m. This was a significant increase from his reported Transfermarkt value of €350k in December 2025.

Our valuation for Ermin Mahmić is driven by multiple consistent reports from mid-2026 detailing Slovan Liberec's asking price. The range is anchored by the reported €7-8 million fee sought from Celtic and the higher demand of over €10 million for interested Bundesliga clubs. The final estimate reflects a likely negotiation outcome given the widespread interest from various European leagues.
