"Lamptey was clearly biased and his deadly mistakes illegitimately gave Esperance a berth in the Champions League final," a statement on Ahli's official site reads.

Ghanaian official Lamptey made some controversial decisions during Sunday's game, which fuelled speculation that he deliberately favored the Tunisian team.

Only seconds after the kickoff, Mickael Eneramo flagrantly extended his arm while diving to poke home from point-blank range, a strike that was enough for the hosts to reach the competition final.

The Nigerian striker handball was blatant and close enough to the linesman to see, but eventually the referee allowed the illegitimate goal to stand.

The Red Devils played over an hour with ten men after Mohamed Barakat was sent off in the first half for thumping Khaled Korbi in the face during a scuffle, which abysmally reflected on their performance.

After the game, many Ahli officials and players blamed the loss on Lamptey.
