The following season was also a positive one, with 32 games played and 6 goals scored. The 2005–06 season was by far Marchionni's best with Parma: he gave great contributions to the team's gameplay, including many assists and many instances of "playmaking". He finished the season with 31 appearances and 4 goals, helping Parma avoid relegation. His talent and relatively young age attracted the keen eyes of the Juventus scouts, and the team did not delay in signing him from Parma. Marchionni joined his new team on free transfer in June 2006.
