Julien Célestine, a 28-year-old French-Italian defender, left Arka Gdynia last week after his contract was terminated by mutual agreement. This allowed him to join a new club without a transfer fee, and he has now officially moved to the South Korean top-tier side Jeju United. Célestine reportedly said that while he had some concerns about his first move to the Asian stage, he was impressed by coach Sérgio Costa and the club's management philosophy, which made him feel it was the ideal place for a new challenge. Shortly after Célestine's departure, Arka Gdynia announced the signing of another centre-back, Serafin Szota. Célestine made 8 appearances in the Ekstraklasa in the 2025/2026 season. According to Transfermarkt, he has a current market value of €300k.
