The UAE's Al Wahda kicked off the campaign with a stunning 2-1 defeat of Saudi Pro League champions Al Ittihad Club while Iran's Tractor had to share points with Shabab Al Ahli in a 1-1 draw.
Despite Al Wahda's Matchday One heroics, the record books are firmly in Tractor's favor with the Tabriz-based side unbeaten in home games against teams from UAE in the competition (W4 D2).
Scoring in continental matches at home has also not been an issue with Tractor having scored in each of its last nine AFC Champions League games at home.
It, however, has failed to keep a clean sheet in each of its last four such games, winning just one (D1 L2).
Al Wahda has not been successful in its previous trips to Iran, having drawn twice and lost four while its win against Al Ittihad was its first victory in an opening tie on the continental stage since 2007.
Despite the odds, the win against Al Ittihad was a morale booster and Al Wahda will head into the tie brimming with confidence.
