"I preferred to resign after being subjected to fierce criticism during the past period," he said after the match.

"I was criticized from people within the club, something which I did not appreciate."

Nevertheless, Zamalek chairman Mamdouh Abbas insisted Helmi would carry on with the Cairo giants.

"Helmi's decision came in the heat of the moment, I'm sure he will continue with us," he said.

Zamalek head coach Ruud Krol is also set to leave for family reasons. A coaching staff overhaul is expected.

"Zamalek board member Mohamed Abou-Allam is negotiating with two coaches as the club seek a replacement for Krol," Abbas added.

French manager Henri Michel, who departed Zamalek in August 2007, is one of the favorites to take over at the club for another stint.
