Al Sadd play Esteghlal of Iran in a one-match qualifier for the AFC Champions League group stage.
Hossam Kamal, Al Sadd's defender, insists it's unfair to play a single game as a decider of who will make it to the AFC Champions League group stage.
Al Sadd will be welcomed by Esteghlal Tehran at the Azadi Stadium in the Iranian capital city on Tuesday, and Al Sadd will have to bring home the victory to advance to the group stage of the most prestigious competition in Asia.
"It will be a tough match," said the 21-year-old at the pre-match press conference in Tehran.
