The Persepolis club has referred its complaint against Estegalal's Albanian winger Yasser Assani to the Court of Arbitration for Sport (CAS) so that the case related to this player's contract can be reviewed by the international authority.
Persepolis believe that a light contract with Estegalal was canceled and re-signed before the start of the season, while that club's transfer window closed.
Persepolis considers this action to be in violation of the transfer regulations and for this reason continues the legal work on the case at the Court of Arbitration for Sport.
Earlier, after the match with Esteghlal, several Premier League clubs complained about the contract situation and the easy way to register with the Disciplinary Committee of the Football Association, and all these complaints were rejected.
Now, Persepolis has referred the case to the Court of Arbitration for Sport demanding to re-examine the state of the light contract and the legality of his presence in the Estegalal group.
