The recently-crowned Egyptian champions sent a letter to Graz, demanding to be given Riad's international clearance as soon as possible in order to play him in the upcoming league and cup matches.
"I hope the international clearance will arrive soon as it is my chance to play and prove myself after seven regulars were rested for the rest of the season," Riad told FilGoal.com on Wednesday.
The 25-year-old midfielder joined Graz in January in a disappointing loan spell as he couldn't play on a regular basis and his side were relegated to the second division after being docked points for administrative problems.
"I have been training everyday since my return to Ahli and ready to participate if the technical staff decided to field me."
Riad also revealed that he intend to fulfill his deal with Ahli, which runs out in two seasons' time.
