Winger Mahmoud Kahraba, who has made a superb start to life at Zamalek after joining in the summer, appears to have angered coach Alex McLeish following a poor display in a league game on Sunday as he was left out of the African Champions League opener away to Cameroon's Union Sportive de Douala.
Although Zamalek said on their official Facebook page that Kahraba was omitted "because of injury", speculation is rife that new Scottish boss McLeish has opted to drop him following another disappointing display in the team's 2-0 victory over Arab Contractors.
Kahraba, a talented and pacy winger, remains Zamalek's top scorer in the domestic league with seven goals but has been criticised for what many fans deemed his selfishness and careless attitude.
Zamalek did not specify what kind of injury the 21-year-old has sustained.
Defender Ali Gabr will also miss Sunday's clash against Douala in the first leg of the Champions League round of 32 due to suspension. Striker Ahmed Mekki, who fell down the pecking order behind Bassem Morsi and Zambian frontman Emmanuel Mayuka, was also out.
League champions Zamalek are representing Egypt in the African Champions League this season alongside runners up Ahly - record holders of the continent's primary club competition with eight titles under their belt.
Zamalek's archrivals Ahly will be also kicking-off this season's bid against Recreativo de Libolo of Angola away on Saturday.
The two Cairo giants have just hired new European coaches - Ahly signed former Tottenham manager and Dutchman Martin Jol while Zamalek landed Scotland's Alex McLeish.
Zamalek 20-man squad:
Goalkeepers: Ahmed El-Shennawy, Gennesh, Amr Salah
Defenders: Hazem Emam, Omar Gaber, Mohamed Adel, Hamada Tolba, Ahmed Dwidar, Mohamed Koffi
Midfielders: Ahmed Tawfik, Maarouf Yussuf, Tarek Hamed, Mahmoud 'Shikabala' Abdel-Razek, Ayman Hefni, Mohamed Ibrahim, Ahmed Hamoudi, Mostafa Fathi
