Mohamed Abou-Treika's first-half strike was enough to hand Ahli a 1-0 victory over arch-rivals Zamalek in the 100th Cairo derby on Monday.

Follow up:
Ahli had the first sight of goal in the 11th minute after some good work from skipper Shadi Mohamed on the right flank.
Flavio stepped over Shadi's cross and the ball went into the path of Abou-Treika, who turned and hit a right-footed shot just over the crossbar.
In the 15th minute, striker Abdul-Halim Ali's low shot was parried by Essam Al-Hadari but none of Zamalek players were able to make the follow-up.
Shikabala raced down the left flank in the 28th minute and sent a fine cross to Ali, who got in front of his marker but his first-time effort went poorly wide.
Abou-Treika put Ahli ahead in the 37th minute following a disastrous defending by Zamalek players.
Hossam Ashour was surrounded by Karim Zekri and Mahmoud Fathallah but managed to release Abou-Treika with a deft pass that beat the offside trap.
The Egyptian international went clear on goal and wrong-footed Mohamed Abdul-Monsef before slotting into the empty net.
Seven minutes after restart, Flavio latched onto Gilberto's through pass and rounded Abdul-Monsef, who had no alternative but to bring the Angolan striker down.
The referee was lenient in dealing with the unfortunate goalie as he opted to give him just a yellow card.
Spot-kick specialist Shadi stepped-up but his shot was superbly blocked by Abdul-Monsef's stretched hands.
Tunisian defender Wissem El-Abdi almost grabbed the equalizer in the 68th minute when he connected with Shikabala's corner at the far post before heading past the advanced Al-Hadari. However, his effort was cleared off the line by Shadi's header.
Gamal Hamza, who was introduced instead of the below-par Ali, had another chance ten minutes later when his powerful shot was denied by Al-Hadari.
Zamalek dominated possession in the rest of the clash but failed to make clear-cut chances as Ahli claimed a precious win before facing Libya's Ittihad in the first-leg of the CAF Champions League semi-final.
