On 12 August 2006, the Iranian Football Federation decided to give the league another name. Since then the league primarily had been known in Iran as "Persian Gulf Cup" (PGC). The Football Federation decided this to promote the Persian naming. The name of the Persian Gulf has been disputed by some Arab countries since the 1960s due to political and ethnic differences between Iran and Arab countries. The football Federation decided also to change the logo of the league. The finally logo was selected from over 130 designs and unveiled on 14 November 2006. Under the leadership of Iranian football legend Ali Daei, Saipa won the 2006–07 Persian Gulf Cup two points ahead of Esteghlal Ahvaz. Until 2007 six different teams won the league title successively. For the first time in history a foreign player became the league's top goal scorer. Nigerian striker Daniel Olerum scored 17 goals in 27 matches for Aboomoslem. The winner of only two seasons before, Foolad, had to relegated to Azadegan League.
