The Egyptian FA have reached an agreement with Austrian referee Robert Shoergenhofer to take charge of the Cairo derby clash between Ahli and Zamalek. The FA's website announced the news on Tuesday, two days ahead of the eagerly-anticipated contest between Egypt's top duo. Shoergenhofer was named after attempts with several other European referees failed due to the holidays and poor weather. The 37-year-old will be assisted by compatriots Andreas Fellinger and Armin Eder. League leaders Zamalek face their arch-rivals with six points clear on top of the table.
