The club's new assistant coach Ayman Mansour was due to hold a meeting with Eno on Thursday but the player didn't arrive, leaving his father, who acts as his agent, present his client's demands.
Eno wants to be given EGP 2 million as a compensation for the past seasons he spent with Zamalek without receiving a substantial amount of money, he believes.
The 26-year-old midfielder also targets a three-year contract extension in order to stay with the Cairo giants.
Eno's demands fuelled rumours that the player has already agreed on a switch to Zamalek's arch-rivals Ahli at the end of the season.
Mansour told FilGoal.com earlier this week that his meeting with Eno is the last chance for the player to strike a new deal with Zamalek and it now seems the negotiations have reached a dead end.
