Ahli defense stalwart Wael Gomaa says it is impossible to deal with Esperance's set-pieces ahead of the Champions League final return leg in Tunis on Saturday. Esperance claimed a positive result away from home when they held Ahli to a 1-1 draw in the first leg, with the visitors' goal scored from a corner-kick. The goal scored by Walid Hichri was Esperance's fifth set-play goal in as many games against the Reds, who conceded a total of seven goals in their history against the Tunisians. “I think it is incontrollable for other teams," Egypt veteran Gomaa told FilGoal.com. “Set pieces are Esperance's main source of danger; other teams really struggle to deal with it. “They were able to make the most of it when they defeated Olympique Béja 2-1 – in the Tunisian league – where their two goals came from set pieces. “Our only way to stop them is to avoid conceding corners or free kicks near the box." Ahli need to win or draw by more than one goal to make it seven Champions League titles as Esperance just need a clean sheet to secure their second straight trophy.
