Watch: Blood, thunder but no goals as Iran, Iraq draw at Asian Cup

Iran claimed bragging rights over arch-rivals Iraq on Wednesday as they finished top of their Asian Cup group after an engrossing but goalless draw at a packed Al Maktoum Stadium in Dubai.

The latest instalment in one of football's great rivalries failed to live up to their classic 2015 quarter-final, won by Iraq on penalties, as a raw and uncompromising first half gave way to a more measured second period.

It meant that Iran, Carlos Queiroz's three-time winners, finished top of Group D on goal difference after their 5-0 thrashing of Yemen and 2-0 win over Vietnam.

Iran welcomed back Brighton's Alireza Jahanbakhsh, last season's Eredivisie top-scorer, from injury as they set about going unbeaten for a 20th straight game at the group stage.

And in a physical first half in front of a deafening crowd, Iran, Asia's top-ranked side, were largely on top but couldn't make their advantage count.

As the challenges flew in, Jahanbakhsh and Iraq's Safaa Hadi both wiped away blood, and Iranian midfielder Saman Ghoddos was lucky not to see red for a stamp.

Iran's Sardar Azmoun came close with a header, Ghoddos saw a powerful drive deflected away and Jahanbakhsh fizzed one over on the rebound.
