The hosts crashed out of the competition after losing 5-6 through a penalty shootout in the return leg match against Vita Club de Mokanda of Congo.
Akwa United who had a 1-0 first leg advantage however lost the return leg by the same scoreline after regulation time.
Meanwhile, Paul Bassey, a CAF instructor and a member of NFF Technical Committee, said he was highly disappointed with the performance of Akwa United.
Bassey said Akwa United was a scapegoat to all the Nigerian clubs playing on the continent this season.
“It is most unfortunate that they have to crash out of the competition this way,’’ he said
