Iraq enjoyed a dramatic start to the men's football section of the Olympics as substitute Ali Jasim secured a 2-1 win against Ukraine in Group B.

Ukraine had taken the lead through Valentyn Rubchynskyi in the 53rd minute in Lyon, but Iraq were soon given the chance to level from the penalty spot.

Aymen Hussein converted in the 56th before Ali hit the winner in the 75th.

Nearly 20 years after their last football win at the Olympics, Iraq staged an epic comeback. After a tense back and forth, midfielder Jasim emerged as the hero, repeating his late-game heroics that propelled his squad to the Paris Games in the first place.

Ukraine were making their Olympics football debut. They will face Morocco on Saturday, while Iraq will take on Argentina, who will have a point to prove after their defeat.
