The 2004–05 season saw Boruc remain Legia's key player and a fan-favourite, again playing in all of the club's league fixtures. Boruc's performances for Legia saw the club extend his contract up to 2012. In March 2005, Boruc was made captain of the side. However, it was another disappointing league campaign for Legia, as they came a distant third behind Wisła Kraków who finished as champions for the third year in a row. Legia's UEFA Cup run was also relatively brief, disposing of FC Tbilisi 7–0 on aggregate in a relatively easy qualifying tie before going out 1–4 on aggregate in the first-round proper to Austria Wien. Despite the lack of silverware, Boruc's form was attracting attention from abroad by the summer of 2005.
