Injuries threaten to decimate Zamalek options ahead of their clash against Dynamos Harare as Junior Agogo has been deemed doubtful for the Champions League game. “Agogo might not be able to participate in the game,” Zamalek coach Reiner Hollmann told a press conference on Wednesday. “He is suffering from knee pain. He is undergoing intensive treatment in order to recover in time for the crucial encounter.” The Ghanaian striker, who scored in Zamalek's 2-2 draw with arch-rivals Ahli, adds to Zamalek worries ahead of Sunday's match. Forward Gamal Hamza, who usually partners Agogo upfront, will miss the match as he serves an automatic suspension. Hollmann will have no choice but to rely on Mostafa Gaafar, Abdul-Halim Ali and Sherif Ashraf although the trio failed to impress this season. There will also be shortage of options at the back. Influential sweeper Hani Saied has been ruled out due to a thigh injury while defender Mahmoud Fathallah remains doubtful as he is nursing a knee problem. Combative defender Amr Al-Safti will be out due to suspension.
