Having defeated Syria 2-1 and Mauritania 1-0, UAE only needed a draw against Tunisia at the Al Thumama Stadium to finish top.

It wasn't to prove costly though as Mauritania, without a point from their earlier two matches, defeated Syria 2-1 with the winner coming in the fifth minute of second half added time at the Al Janoub Stadium.
Mauritania took the lead through Mohamed Soueid in the 50th minute but Syria's reply was almost immediate with Mahmood Albaher equalising two minutes later.
Hemeya Tanji, however, ensured Mauritania ended their campaign on a high with the winner deep into added time.
