Only a win would do for UAE, having lost 2-0 to the Kyrgyz Republic on Friday after having kicked off their campaign with a 5-0 victory over Brunei Darussalam.
The Central Asian side’s persistence was rewarded in the 71st minute with forward Saied Saharkhizan slotting home.
A desperate UAE tried to find their way back but their hopes were dashed in the sixth minute of added time with Amir Ebrahimzadeh scoring Iran’s second.
Midfielder Mohammadreza Torabi put Iran ahead in the 23rd minute and that paved the way for total domination as Ebrahimzadeh (27th) and Mojtaba Fakhrian (45+1) secured a comfortable lead going into the break.
