The club's board will evaluate his performance during the past period.

An internal source told FilGoal.com that Helmi Toulan and Mahmoud Saad are the frontrunners to succeed Krol should Zamalek sack the Dutchman.

The source also told that Krol may stay and there could be some changes in the technical staff.

Under Krol's helm, Zamalek conceded five defeats and dropped to the fifth place of the Egyptian standings with 27 points, 15 behind leaders Ahli.
