Ismaili players felt a sense of frustration upon learning the FA's decision to put off their Egyptian Premier League clash with Ahli, according to assistant coach Abou-Taleb Al-Essawi. The Dervishes were supposed to clash with their bitter rivals behind closed doors at Cairo Stadium on Tuesday, only for the match to be postponed for security reasons. “We've reached a high level of concentration inside the team, but the decision frustrated us as it disrupted our preparations for the match,” Al-Essawi told FilGoal.com. “We understand well the ongoing conditions the country is passing through and the importance of maintaining security; in the end we respect the decision. “We still insist on staging the game behind closed doors whatsoever.” Ismaili are currently four points behind leaders Ahli but the former have a game in hand. Clashes between both teams have rarely been free of tension off the field during the past few years.
