The Dervishes paid Sion $600,000 for the Egypt number one, despite the fact that he is subject to a lengthy ban by FIFA.

After he moved illegitimately from Ahli to Sion last year, Al-Hadari was handed a four-month ban by FIFA's Dispute Resolution Chamber for violating his contract.

However, the suspension was frozen by the Court of Arbitration for Sport (CAS) upon the keeper's appeal and Ismaili are hopeful it remains like that.

"We made some impressive signings this summer in Al-Hadari, Ahmed Sedik, Ahmed Ali, Ayman Ramadan and Ahmed Abou-Mosallam," Ismaili chairman Nasr Aboul-Hassan said.

"I think if Al-Hadari was fined it wouldn’t be a problem for us because Sion will pay.

"I am also optimistic that Ahli won't seek further action against him especially that our relationship with them has become better of late."

Al-Hadari is expected to start for Ismaili when they host newcomers Mansoura in the Egyptian Premier League opener at the weekend.
