O. Kubiak

In April 2026, reports indicated Slavia Praga submitted an official offer worth €1,000,000, including bonuses, which was rejected by Arka Gdynia as unsatisfactory. Around the same time, the player's market value was estimated by Transfermarkt to be €500,000.

Our valuation is driven by the concrete €1,000,000 offer from Slavia Praga in April 2026, which was rejected by Arka Gdynia. The selling club's stated desire for a 'significantly higher' sum, combined with Oskar Kubiak's young age and long-term contract until 2028, firmly places his value above the rejected bid. The interest from other clubs further supports a higher final transfer fee.
