The match will be held at the Al Shabab Stadium in Riyadh, Saudi Arabia on Tuesday.
Debutant Lebanon has only pride to play for after losing 3-2 to Uzbekistan and 4-3 to Korea Republic, and head coach Taha will work on ensuring his players are ready for another tough outing.
“Our players need to strengthen their mindset, and not think about the match against Korea Republic (where they led twice before losing),” said Taha. “We have a good team and I want them to play their final game in the style of Lebanese football.
“We faced 2018 champion Uzbekistan, 2020 winner Korea Republic and now a strong Iranian side,” he added. “But we knew from the beginning that this would be a very difficult group.”
