Both sides came close to breaking the deadlock numerous times but ultimately had to settle for a share of the points at the Yadegar-e Emam Stadium in Tabriz.
Al Wahda had kicked off its campaign with a stunning 2-1 defeat of Saudi Pro League champion Al Ittihad Club while Tractor had to share points with Shabab Al Ahli in a 1-1 draw.
Matchday Three will see Al Wahda take on Qatar’s Al Duhail on October 20 while Tractor will look for its first win against Sharjah of the UAE on the same day.
