Ten-man Shabab Al Ahli snatched a 1-0 home victory over Al Wahda in the first leg of the Pro League Cup semi-final at Rashid Stadium on Tuesday.
After a largely quiet first half, the hosts posed their first real threat on Al Wahda goalkeeper Rashed Ali ten minutes before the teams headed to dressing rooms for the break after some great teamwork between Mohammad Juma and Thomas Olsen ended with the former chipping the ball over the goalkeeper but his effort went just wide.
At the hour mark, Juma curled an excellent effort from a well-taken free-kick, but Ali brilliantly saved it.
Tahnoon Al Zaabi came close to giving the visitors the lead when he fired a powerful left-footed shot from outside the box, but his effort hit the post in the 71st minute.
Shabab Al Ahli had to finish the game with ten men as defender Mohamed Jaber was sent off in the 73rd minute with a straight red card after elbowing Khalil Ibrahim who was through on goal.
Ten minutes from time, substitute Gustavo broke the deadlock when he picked up Olsen's pass on the edge of the penalty area, before curling a right-footed effort into the bottom right corner to win it for Shabab Al Ahli.
The two sides lock horns again at Al Nahyan Stadium in the second leg of the semi-final on Tuesday, March 6.
