Zamalek's Ahmed Hassan admitted that his side will be facing a tougher job when they clash with Ahli in the Champions League next week. The Cairo giants lock horns on Sunday, with Ahli on top of the group and Zamalek bottom. Facing his former club for the first time, Hassan knows that the Whites are in dire need for a win to make up their first-day defeat. “I believe Zamalek's mission is harder after we lost our Day 1 encounter against Ghana's Berekum Chelsea," the Egypt captain told Cafonline.com. “We need to win to keep our chances alive for a semi-final spot. On the other side Ahli also are looking for victory to raise their points tally so this makes the game a very difficult one for both sides. “Ahli are a big team and I believe they are in high spirits after beating Mazembe in match day 1 but these derbies are hard to predict and have no particular or special format." Hassan missed the Chelsea defeat through suspension but is expected to start against the club that released him last summer.
