Zamalek (in white) must beat Ahly in Saturday's game

The destination of the Egyptian league title could be decided on Saturday when arch-rivals Zamalek clash with Al Ahly in Cairo.

Ahly have a five point lead over Zamalek with five games left to play before the end of the season.

Zamalek will be hard pressed to win the game in order to close the gap behind Ahly.

After a three-week suspension the match will be the high point when league action resumes.

Security will be beefed up because there are often flash-points.

Earlier in the season both sides drew 2-2.

The match will be officiated by a German referee, Helmut Fleischer.

Foreign referees have handled the derby for over 40 years.
