The 2005-06 campaign was a season of struggle and eventual consolidation for Saint-Étienne as Les Verts finished 13th in Ligue 1 under manager Élie Baup. Following a successful return to the top flight, the team found consistent form difficult to maintain, exemplified by top scorer Frédéric Piquionne's tally dropping to just 6 league goals. Despite this, the Stade Geoffroy-Guichard faithful enjoyed a spectacular 3-0 victory over Paris Saint-Germain, offering a flash of brilliance in a difficult year that solidified the club's position in the top division despite a disappointing overall run.
