Iran knows it can't afford to slip-up against Cambodia as anything other than three points will mean its hopes of winning Group C will suffer a tremendous setback.
Team Melli, has however, shown consistency since the resumption of the Asian Qualifiers, scoring a 3-1 win over Hong Kong before beating Bahrain 3-0 to move into second place.
Five different players found the back of the net in the six goals scored in those matches, with Sardar Azmoun scoring twice against the Bahrainis.
Having defeated Cambodia 14-0 when the two met in October 2019, head coach Dragan Skocic will expect nothing less than three points.
While the spotlight will be on Iran, Cambodia has nothing to lose as it heads into the final match of its campaign, the-afc.com reported.
With its hopes of playing in the AFC Asian Cup China 2023 Finals now depending on a playoff, the Southeast Asians will aim for an improved performance against Iran as it builds on its experience.
The match will be held at the Bahrain National Stadium in Riffa on Friday.
