Tunisian side Esperance have said they were very surprised about the decision by the Confederation of African Football (Caf) decision to replay the second leg of the African Champions League final.
They won the cup after Moroccan opponents Wydad Casablanca left the pitch after an equaliser they scored was disallowed.
Esperance were leading 1-0 at the time.
“The club’s management will hold an urgent meeting to appeal against Caf’s decision with the relevant international bodies and will take all legal measures to preserve its rights,” Esperance said in a short statement.
Caf has said the second leg will be replayed at a neutral venue.
The 1-1 draw from the first leg in Morocco stands.
The replay will be after the Africa Cup of Nations in Egypt, which ends on 19 July.
A Caf statement said “conditions of game and safety were not met” in the second leg and made clear Esperance players must return their winners’ medals as well as the trophy.
