The Whites staggeringly lost 1-0 to MCDR on Thursday, a result that left the league leaders level in points with their arch-rivals Ahli.

Zamalek are to file a complaint against Yasser Mahmoud, who refereed the match and is accused of making fatal refereeing mistakes.

he didn't give Zamalek a penalty kick when MCDR striker Hussein Hamdi handled the ball in the area.

He also disallowed a Mohamed Abdul-Shafi goal through offside, although TV replays showed that the player was onside.

"Although the MCDR loss was hard as a result of the refereeing unfairness, we pledged to do our best in the upcoming league games," he told Zamalek's official website.

"We are seeking to win the league title and dedicate it to our loyal fans who back us everywhere."
