Having lost the 2017 AFC Champions League semi-final 6-2 on aggregate to Saudi Arabia’s Al Hilal SFC, Persepolis went one better the following year by making the final - only to come up short against Kashima Antlers, who followed up a 2-0 win in Japan with a stalemate at Azadi Stadium in Tehran.

Eleven months and five days since Bahrain’s Riffa SC beat Chennai City of India 1-0 in the first preliminary round, it is down to two iconic sides and one clash that will determine the winners of the 18th edition of the AFC Champions League.

Both Persepolis and Ulsan Hyundai are appearing in their second final, with the Koreans having defeated Al Ahli Saudi FC to win the 2012 title and Persepolis having lost the 2018 final to Japan’s Kashima Antlers.

Under normal conditions, the Korean club and West zone semi-final winners Persepolis FC would be gearing up for 90 minutes each in front of their own fans, but apart from a few lucky fans in Doha, the 2020 decider will be run and won in one night, and experienced largely through screens everywhere from Ulsan to Tehran.
