Celtic have asked Zamalek to allow Shikabala join the club for a medical from the period of Wednesday August 26th until Saturday the 29th.
The enquiry also included that the Bhoys are ready to acquire the services of the 23-year-old wizard, for a fee named by the Cairo club.
However, Zamalek have yet to reply to Celtic's bid, neither have they made an official statement about the matter.
Shikabala is currently nursing a groin injury and is not expected to be fit before three weeks.
The transfer deadline is on Monday August 31st.
Celtic have shown interest in Shikabala last February, as revealed by agent Georg Stangassinger. A transfer of around £1million was mentioned.
The Egypt international has also been linked with moves to Blackburn Rovers and Mainz, but Zamalek rejected his departure.
