Although Mostostal fans dreamed of regaining the place at the top of the league, the 2005–06 season was the worst in club's history. Wojciech Drzyzga has been dismissed, after a series of 10 defeats in a row, and so far acting as his assistant coach, Andrzej Kubacki has become the new head coach. The club from Kędzierzyn-Koźle was not able to save that season and finished 8th in the championship.
