There seems to be a war of words brewing between the two biggest clubs in Egypt, with Ah Ahly now reportedly filing a 13th complaint against Zamalek president Mortada Mansour.
The two Cairo-based clubs are involved in what is widely considered to be one of the craziest rivalries in football, and tensions between the Egyptian giants are believed to be at an all-time high.
According to KingFut, Zamalek chief Mansour has been vocal on Facebook about his feelings towards his Al Ahly counterpart Mahmoud El-Khatib.
In a recent social media tirade, Mansour claimed that referees have, for a long time, favoured the Red Devils, and that Farouk Gaafar, a former Zamalek player, was far better than El-Khatib during their playing days.
Mansour continued his rant by insisting Al Ahly have been trying to tarnish their rivals' reputation.
As a result of this, El-Khatib has reportedly lodged a formal complaint against Mansour to Egypt's Public Prosecutor for a 13th time.
