City's stance means Marmoush may miss up to 10 matches with the team if Egypt progresses to the latter stages of the tournament.
Egypt has a friendly match against Nigeria on December 14, but Manchester City has a league game against Crystal Palace on the same day.
As a result, Manchester City will require Marmoush's presence for the Palace match.
However, Marmoush will be released to join Egypt's squad after the game.
