Despite being introduced with just 15 minutes remaining, newly-signed Ali turned on the tables for his side after being involved in Ahmed Gaafar's opener before bagging a brace himself to complete the rout.

Twenty-one-time cup champions Zamalek now meet Gaish, who overcame Aluminum on penalties, for a place in the competition's final.

Despite dictating play in the first half, the Whites failed to translate their dominance into goals, thanks to some poor finishing in front of goal.

It wasn't until the 75th minute when Gaafar headed home a Hazem Emam cross after combining with Ali, who was introduced just one minute earlier.

Ali doubled the lead six minutes later, slotting home Gaafar's low cross from the left to score on his second game with his new club.

Former Ismaili frontman Ali then ensured the win with five minutes from time, netting on the rebound a Shikabala looping effort that was thwarted by the crossbar.
