Michal Sáček transferred to Górnik Zabrze without a transfer fee due to his expiring contract with Jagiellonia Białystok. The transfer was influenced by personal reasons, as Sáček wanted to be closer to his family, with locations in Zabrze, Trenczyn, and Prague being nearby. The club presented him with specific terms that met his expectations and budget. Lukas Podolski played a role in convincing Sáček to join by discussing the potential and positive environment at Górnik.

Czech defender Michal Sáček joined Górnik Zabrze on a free transfer from Jagiellonia Białystok. He signed a contract valid until June 30, 2028. The sporting director, Łukasz Milik, highlighted the difficulty of acquiring Sáček due to his achievements with Jagiellonia and Sparta Prague. The opportunity arose unexpectedly, leading to contact and successful negotiations. Sáček was sought for his defensive skills and ability to contribute offensively.

Górnik Zabrze is set to announce the signing of Michal Sáček from Jagiellonia Białystok. Despite Jagiellonia Białystok's effort to retain him, Michal Sáček decided to join Górnik Zabrze to be closer to home. Tomasz Włodarczyk reported this in the program 'Okno Transferowe'. He will undergo medical tests before signing a contract to play for the Ekstraklasa club until at least June 30, 2028. Michal Sáček moved to Poland from Sparta Prague in February 2023 and played 34 matches with five assists last season.

Michal Sáček has departed from Jagiellonia Białystok, but there is a possibility he could remain in the Polish Ekstraklasa by transferring to Górnik Zabrze, according to reports from iSport.cz. Despite Sáček's recent health issues, Jagiellonia expressed a desire to retain the 28-year-old for a longer period, but their contract extension proposal was not well-received, resulting in his confirmed departure from the club. Sáček, who was absent for nearly the entire spring season due to a serious injury, was succeeded by Norbert Wojtuszek at Jagiellonia. Both the club and Sáček have acknowledged the conclusion of their partnership. Having played 86 matches for Jagiellonia, Sáček's potential transfer to Górnik Zabrze, following the path of Jarosław Kubicki, marks a notable internal transfer within the Ekstraklasa. Górnik Zabrze, actively participating in the transfer market, has already added Theodoros Tsirigotis, Wiktor Nowak, Gabriel Barbosa, and Natan Dzięgielewski to their team.
