During the winter break, Ondřej Zmrzlý was linked with Sigma Olomouc. At one point, his return to Haná was considered finalized, but the move ultimately did not happen. The transfer did not progress and no agreement was reached. Slavia did not include him in their plans.

In January, foreign media reported that Ondřej Zmrzlý of Slavia Praga was expected to move on loan to Sigma Ołomuniec during the winter transfer window. However, the move was not subsequently confirmed.

An agreement has been reached for the loan of Ondřej Zmrzlý from Slavia Praga to Sigma Ołomuniec with an option to buy, according to 'iSport'. An official announcement is expected soon.

It was initially assumed that Ondřej Zmrzlý could rejoin Sigma Olomouc, and the Moravian club is one of the teams with serious interest in the player. However, they are not the only ones. According to "iSport", Górnik Zabrze has joined the interested clubs. The group of interested clubs also includes second-division side Holstein Kiel. Zmrzlý, a Czech left-back, is expected to lose his place in the Slavia Praga squad due to the return of David Jurásek, and Slavia is said to be open to a loan with an option to buy the 26-year-old. The two-cap Czechia international joined Slavia Prague from Sigma Olomouc in January 2024 for a reported €1.0 million fee and has a contract running until June 2027. This season, he has made 11 league appearances, providing one assist. His current market value is estimated by Transfermarkt to be €1.5 million.
