In Lechia's 3rd season back in the top flight, it was another season of consolidating their Ekstraklasa status. In the 2010–11 season the team once again finished in 8th place. It was, however, a more positive season that showed progression for the team as a whole. It was the first time since their promotion back to the top league that Lechia had won more games than they had lost, finished with a positive goal difference, and Lechia player Abdou Traoré finished joint runner up for most goals that season. And for the second season in a row Lechia reached the semi-finals of the 2010–11 Polish Cup, before losing 5–0 to Legia over the two legs. This was the last season in which Lechia played at the MOSiR Stadium, the stadium in which Lechia had played all of their home games since their formation in 1945. The last game to be played at the stadium was the final game of the season against Zagłębie Lubin, a game in which Lechia lost 2–1.
