With a crucial period of fixtures incoming for the White Knights, pressure is reportedly building up on head coach Milutin Sredojevic and his technical team.
And now Mansour, known for his controversial and outspoken nature, has looked towards unorthodox methods of getting the squad to focus on their ambitious targets for the season.
In a video, released on his official Youtube channel, the 67-year-old issued a lengthy speech to the team, with one of the issues being their social media habits.
This after key midfielder Tarek Hamed posted a cryptic Instagram story over a reported wage dispute with the club - which has since been adressed with a lucrative new contract.
"None of you are allowed to have a Facebook page," Mansour said, as translated from Arabic.
"Pick between Zamalek and your Facebook and Instagram page.
"Whoever opens a social media page I will fine him half his salary, and every time you post you will be fined."
Zamalek face off against El Mokawloon on Saturday after the Cairo derby with Al Ahly was postponed due to reported security concerns.
