Hosts United Arab Emirates ended Kyrgyzstan's fairytale with a controversial extra-time penalty to reach the Asian Cup quarter-finals on Monday.

Substitute Ahmed Khalil was UAE's hero on an angst-ridden Abu Dhabi night as he blasted home from the spot in the first additional period to set up a meeting with the Socceroos in the last eight.

Less than a quarter of an hour earlier Kyrgyzstan substitute Tursunali Rustamov had stunned the home side when he snatched a dramatic stoppage-time equaliser at the end of a nail-biting contest.

It had taken the Emirates just 14 minutes to break through as Khamis Esmaeel headed in an Ismail Matar corner.

Plucky Kyrgyzstan refused to go unnoticed on their Asian Cup debut, however, and the White Falcons equalised midway through the first half when Mirlan Murzaev squeezed the ball in from a seemingly impossible angle.

Kyrgyz captain Valery Kichin then gave UAE a scare when his curling shot crashed against the crossbar.

But Ali Mabkhout volleyed the 2015 semi-finalists back in front with his third goal of the tournament after some horror defending from Mustafa Iusupov.

That looked to have ended Kyrgyz defiance until Rustamov headed home in the dying seconds to force extra time.

But after Mabkhout had tumbled in the box under minimal contact, the Asian Cup hosts were awarded a penalty that was hotly disputed -- for the second time in this tournament.

Grobbelaar impression

Khalil kept his cool though and drilled home the spot kick on 103 minutes to give UAE a shot at avenging their semi-final defeat by Australia four years ago.

There was still time for Baktyiar Duishobekov and Rustamov to hit the woodowork, but the Emiratis somehow clung on to give themselves a shot at avenging their semi-final defeat by Australia four years ago.
