Esperance de Tunis interim coach Anis Boussaidi is hoping to pull what will arguably be the biggest CAF Champions League surprise when his side faces Al Ahly, in the return leg of the CAF Champions League semifinal on Friday 19 May from 10 pm EAT in Cairo, Egypt.The former Tunisia international was handed the team earlier this week following Nabil Maaloul’s resignation last week after his side was hammered 3-0 at home by the record African champions, and the return leg may equally prove to be an uphill task as Al Ahly have had a near perfect home record in recent years.##NAJAVA_MECA_7261722##The match is between Al Ahly, with ten titles to their name, and Tunis, who have bagged the African title four times. The aggregate winner of the two-legged tie will face the winner of the tie between Mamelodi Sundowns and Wydad Casablanca.Ahead of the match, the tactician refused to rule his side out of the tie just yet. “The heavy defeat in the first leg does not reflect the true level of my players. Players are determined to perform well and defend their reputation. Nothing is impossible in football,” he told the club’s official website on Thursday ahead of the game.Al Ahly coach Marcel Koller, on the other hand, remained cautious despite having what looks like an unassailable away advantage.”League is not on our minds” – Matano focused on Ulinzi in Mozzart Bet Cup semifinal”We are so happy to win 3-0 away from home. However, that doesn’t mean we have already qualified for the final,” Koller told the club website.”Nothing is decided yet. We saw when Liverpool made a comeback against Barcelona by scoring four goals. Also, Juventus managed to score three times away from home against Real Madrid. We should not imagine that things have been decided. We should not underestimate Esperance de Tunis in the second leg and be fully concentrated because everything is possible in football,” he added.
