Oman, seeking a third title, got off to a dream start with Abdulrahman Al Mushaifri nodding home Ali Al Busaidi's cross in the 17th minute.

Both teams had chances after that but Bahrain's determination paid off in the 79th minute when Marhoon was brought down in the box by Jameel Al-Yahmadi, with the former then firing home from the spot.

Bahrain were ahead seconds later, with Marhoon advancing to the left byline once more and looking to pull back for his teammates in the area.

Instead, the ball was diverted into his own net by Mohamed Al-Musalami to spark wild celebrations among the Bahrain fans in the Jaber Al Ahmad International Stadium.
