Mateusz Wieteska might leave during the winter transfer window, as Nicolò Schira has confirmed. Previously, the media had linked the Polish defender with a potential move to Real Valladolid, a team in the top tier of Spanish football. Recently, Italian media reported that Wieteska is being considered by Real Valladolid, although the club is currently at the bottom of the league table. The Polish international's contract is valid until June 30, 2027, making negotiations challenging for interested clubs, as Cagliari will aim to secure the most favorable transfer fee possible.

Real Valladolid are actively seeking a center back for the January transfer window, with Mateusz Wieteska, the Polish defender from Cagliari, among the potential targets under consideration.
