Ismaili chairman Yehia Al-Koumi insists on the club's right to keep Strasbourg-bound midfielder Hosni Abd-Rabou for the next season. The Egypt midfielder confirmed on Sunday that he will join Egyptian champions Ahli after the French side rejected Ismaili's offer to land him permanently. However, the Ismaili president is adamant that Abd-Rabou is bound to the Ismailia-based club and should go nowhere without Ismaili's acknowledgement. "Abd-Rabou is an Ismaili player and will stay with us, he can't move without the club's permission," Al-Koumi told FilGoal.com on Monday. "I have the documents that prove our right in the player, he has a contract at Ismaili and he will not leave before his contract expires." Ismaili were obliged to pay 500,000 Euros to Strasbourg at the deadline of June 15th in order to acquire the on-loan midfielder permanently, but the French side insisted that nothing was delivered. "I possess the proof that Strasbourg received their fees in full," Al-Koumi added. Ismaili started the process of filing a complaint to FIFA against Strasbourg on Monday, claiming their right in acquiring the services of the midfielder.
