Egyptian league holders Ahli have been drawn with Cairo rivals Zamalek in a tough CAF Champions League group. The draw for the last eight was made on Tuesday in Cairo, with the city's top duo facing off in Group B, which also included the mighty Mazembe of DR Congo. Ghanaian champions Berekum Chelsea complete the four teams of the tough group. Group A paired holders Esperance with Tunisian rivals Etoile Sahel, while Algeria's AS Chlef were the third north African team in the group, with Nigeria's Sunshine completing the pool. The first round will start next month, with Ahli hosting two-time champions Mazembe and Zamalek visiting debutants Chelsea on July 6-8. Zamalek will then entertain Ahli in the second round as both teams clash again in August.
