Zamalek chief Tarek Hashish admits Galatarasay have a permanent option for Mostafa Mohamed.

The striker, outstanding so far with Gala, is on-loan in Turkey to the end of this year. His form has attracted rival interest from Crystal Palace.

Hashish says Galatasaray can activate the buyer's option to December 31, 2021. Hashish also underlined that if Galatasaray activates the option, then it will have to pay $4 million by July 2022.

Hashish also stated that in case of the permanent transfer of Mohamed to Galatasaray, 15% of the next sale will be paid to Zamalek.

Galatasaray hired the 23-year-old young striker for $2m for a year and a half.
