The match is underway
Ahmed El-Shennawi, Hosni Fathi, Mahmoud Hamdi, Ali Gabr, Mohamed Nassef, Maarouf Yussuf, Ibrahim Salah, Tarek Hamed, Ayman Hefni, Mohamed Ibrahim, Bassem Morsi

In a last-minute change, Stanley is replaced with Mohamed Ibrahim in Zamalek's starting line-up. The Nigerian was ruled out after failing to completely recover from injury.
18:45 Fifteen minutes remaining before kick-off. Egyptian fans are glued to their seats!
18:30 No susprises in Ahly's starting XI. They play with a lone frontman in Marwan Mohsen, supported by three attacking midfielders in Abdallah El-Said, Moemen Zakareya and Walid Soliman.
18:00 Zamalek's starting XI includes lone striker Bassem Morsi and Nigerian deep-lying forward Stanley Ohawuchi. They are both declared fit.
17:45 The starting line-ups are expected to be announced shortly. Zamalek fans are still anxious over the fitness of their key players.
17:00 Despite Zamalek's assertions over the availability of key duo Bassem Morsi and Ayman Hefni ahead of the game, reports are saying they might not be included in the starting line-up. Nigerian forward Stanley Ohawuchi is also doubtful.
16:30 Striker Bassem Morsi, who seems to have finally captured his form of late, has been cleared to take part against Ahly after missing the Sharqeya win through injury, with dazzling playmaker Hefni also ready to play after missing last week's league game.
16:00 But Helmi will lament the absence of right-back Osama Ibrahim due to automatic suspension, after the defender's performance has notably improved of late as he opened the scoring in the 2-0 win over Sharqeya with an audacious run into the box.
15:30 The return of fit-again playmaker Mohamed Ibrahim in particular has come as a boost for Zamalek, with the flamboyant midfielder registering two assists in four league games since making his comeback from injury.
15:00 Despite spilling two vital points away at minnows Aswan in Helmi's second game in charge, Zamalek's displays slightly improved in their past two games against El-Entag El-Harby and newcomers Sharqeya.
14:30 The decision to reinstate Helmi came following a run of unconvincing league displays under former boss Moemen Soliman and caretaker manager Mohamed Salah – who remains in his post as assistant coach.
14:00 Mohamed Helmi, who was appointed as Zamalek's manager for a second spell late in November, will be keen to beat Ahly this time around, after seeing a dominant display from his side against Ahly last season end with a goalless stalemate.
13:30 Despite finally being able to break their Ahly jinx, Zamalek's wins only came in the domestic cup, with the two league games between both finals ending in a 2-0 win for Ahly and a scoreless draw.
13:00 Their Egypt Cup feat was repeated again the following season, when another 3-1 final victory against Ahly secured Zamalek their second domestic cup in a row at the expense of their bitter foes.
12:30 The Whites had already managed to break their Ahly hoodoo with a 2-0 Egypt Cup final win under former manager Jesualdo Ferreira in 2015, having failed to beat their perennial rivals in 21 consecutive games in all competitions.
12:00 Zamalek will be looking for their first Egyptian league win over arch-rivals Ahly since May 2007 when both sides face off in a mouth-watering derby clash at Cairo's Petrosport Stadium on Thursday.
Stay tuned; the match is due to start at 19:00 CLT (+2 GMT)
