The 2004–05 season was frustrating for the midfielder, who was sidelined for two months by knee and head injuries and first considered retirement in April 2005. Although Juventus won Serie A titles that year and in 2006, the titles were revoked after the "Calciopoli" match fixing scandal. After the 2005–06 season, which ended with Juventus' relegation from Serie A despite its first-place finish, many stars (such as Fabio Cannavaro and Lilian Thuram) left the club and the remaining players' future was uncertain. After the 2006 World Cup, Nedvěd dispelled rumours about his departure by reiterating his desire to help Juventus regain promotion to Serie A, citing his family and his commitment to the club as reasons for his decision. He received a five-match ban after a red card against Genoa in December 2006, and repeated his threat to retire. However, he remained with the club until the end of the season and scored 11 league goals in the 2006–07 Serie B.
