Sfaxien claim that Zamalek haven't paid an installment of the deal which was due to be given to the CAF Champions League runners-up 20 days ago, Tunisian newspaper Al-Sabah said on Tuesday.

The Tunisian side will have the player back at their disposal in case Zamalek fail to pay the fee, the paper added.

El-Abdi joined Zamalek in the January transfer window on a two-year deal for $400,000 and soon established himself as a key element of the team's defense.
