 2005–06 Süper Lig

The 2005–06 Süper Lig season began with Turkcell signing a 5-year sponsorship deal with the Turkish Football Federation to name the league Turkcell Süper Lig.Since Turkey dropped from tenth to eleventh place in the UEFA association coefficient rankings at the end of the 2004–05 season, the champions will not directly be entered into the group stage of the UEFA Champions League any more, but rather have to begin in the third qualification round.The season also saw a first in Turkish football; for the first time in history the team that entered the last week first, Fenerbahçe, failed to win the title.
