Ariel Mosór

In February 2026, reports indicated GKS Katowice was prepared to make a permanent offer for 'several hundred thousand euros', which was rejected by Raków Częstochowa as unsatisfactory. The player's market value was estimated by Transfermarkt at €1.20 million in December 2025, down from a reported €1.50 million in September 2025. His most recent completed transfer was from Piast Gliwice to Raków Częstochowa in August 2024 for a fee of €1.5 million.

Our valuation is driven by the significant €1.5M fee Raków Częstochowa paid for Ariel Mosór in August 2024, contrasted with his subsequent lack of playing time. A reported bid of 'several hundred thousand euros' from GKS Katowice in early 2026 was rejected, setting a floor for Raków's valuation. The range reflects a likely loss for the selling club, capped by his declining market value, with the estimate representing a plausible compromise.
