Legia Warsaw was one of the teams interested in signing Polish midfielder Oskar Kubiak from Arka Gdynia, which was recently relegated, but the player is now considered more likely to move to Slavia Praga. Other potential destinations for the 19-year-old player were Sankt Gallen and an unnamed Silesian club. The possible transfer to the Czech team is connected to a strategic partnership that was recently established between Arka Gdynia and Slavia Praga. Arka Gdynia had previously hoped to receive a transfer fee of over one million euros for the player. Kubiak has 2 caps for the Poland U20 team and his contract with Arka Gdynia is valid until June 30, 2028. During the 2025/2026 season, he scored a total of 17 goals and made 6 assists in the Ekstraklasa and Betclic 2 Liga combined. Transfermarkt estimates his current market value to be €1.50m.
