Doha, Qatar: Umm Salal fought back after conceding a first-minute goal to see off spirited Al Bidda 3-1 in extra time and move into quarter-finals of the Amir Cup at Abdullah Bin Khalifa Stadium yesterday. Qatar SC also reached the last eight stage after ending Al Waab’s debut appearance in the tournament with a 2-0 victory. Debutants Al Bidda got off to a flying start as Yousef Ahmed put them ahead shortly after the kick off, stunning the Orange Fortress with a brilliant strike into the right corner from outside the box. Oussama Tannane leveled for Umm Salal in 12th minute, finding the right corner off a free kick. Al Bidda could have regained the lead but Bright Enobakhare failed to beat Umm Salal goalkeeper Landing Badji in a 21st minute penalty. Despite several exchanges between the two sides, the scores remained unchanged taking the showdown to extra time where fatigue seemed to have affected Al Bidda as Umm Salal put the game to bed with two quick goals. Lucas Joao put them ahead with a header from a close range off Ali Afif’s assist three minutes into extra time, with Kenji Gorre sealing the hard-fought win with a low drive after receiving a long ball in 96th minute. Umm Salal will determine their quarter-final opponents as Al Gharafa play Al Ahli in their Round of 16 clash today. At the Jassim Bin Hamad Stadium yesterday, Bruno Tabata gave Qatar SC lead with a 31st minute spot kick, slotting in the centre of the net after referee awarded them a penalty following Abdurahman Mohamed Ragab’s foul against Ben Malango. Al Waab also created opportunities in the match mostly dominated by their opponents but their best chance came in the 77th minute when Qatar SC goalkeeper Sataa Abdulnaser made a mistake but Bernard Babacar Faye failed to capitalise on the error. Substitute Ali Awaad sealed Qatar SC’s win style in sixth minute of stoppage time, unleashing a powerful shot from almost 10 yards outside the box, leaving no chance for goalkeeper Mohmad Muntazar. Qatar SC will face the winners of tomorrow’s game between Al Rayyan and Al Khor.
