Overview
- Multiple outlets reported on Aug. 21–22 that Celtic are closing in on a deal for 21-year-old Ermin Mahmic but no official transfer has been announced.
- Reports disagree on the price and structure: outlets cite a base fee around £6–7 million, offers of £7 million plus add-ons, and an £8.5 million headline figure.
- Mahmic has been left out of recent Slovan Liberec matchday squads and attended a match to say goodbye to fans while Liberec’s manager confirmed he is still training with the group during negotiations.
- The Bosnia international boosted his profile at the 2026 World Cup with two goals and produced roughly 28–30 club appearances last season with seven to eight goals and several assists, drawing interest across Europe.
- If completed, the sale would likely be a record transfer for Slovan Liberec and would test Celtic’s plan to add creative midfield options under Martin O’Neill while raising questions about how Mahmic will adapt to the club’s defensive and positional demands.
