Zamalek midfielder Mohamed Aboul-Ella said on Sunday that he might miss the next league game against Mahalla through injury. Aboul-Ella limped off the pitch early in the second-half during his side's 2-1 defeat against Ahli on Saturday. He told FilGoal.com that he picked up a knock in his heel and the resulted bruise is likely to rule him out of the trip to the delta city. Aboul-Ella was deployed as a playmaker in the Cairo derby and he launched raids from the left and right, providing strikers Gamal Hamza and Amr Zaki with defense-splitting passes. Osama Hassan replaced Aboul-Ella in the 51st minute and the former ENPPI left-back curled Zamalek's only goal home after just four minutes of his introduction.
