Team Melli have never made it beyond the opening stage and another early exit is expected, judged on the Iran World Cup 2018 odds.
Iran have made four previous appearances at this tournament, with their only win from 12 games coming against the USA in 1998.
Four years ago, they opened with a goalless draw against Nigeria and only lost 1-0 to Argentina after an injury-time strike by Lionel Messi.
However, a 3-1 defeat to Bosnia and Herzegovina ended any hopes of reaching the knockout rounds for the first time.
Qualifying for Russia 2018 went smoothly, though, with Iran going unbeaten through their Asian pool to finish seven points clear of South Korea.
Remarkably, they did not concede a single goal in the first nine fixtures, before closing with a 2-2 draw versus Syria.
There will be some positive Iran World Cup 2018 betting tips and predictions prior to a winnable opening game against Morocco.
However, it will be a major surprise if they can take anything from subsequent clashes with Spain and Portugal.

Iran do have an experienced and much-respected head coach at the helm in Queiroz, who is the only manager in the country’s history to lead them to two World Cup tournaments.
The 65-year-old previously managed his native Portugal at South Africa 2010, while he was a long-time assistant to Sir Alex Ferguson at Manchester United and briefly took charge of Real Madrid.
On the pitch, big things are expected from Sardar Azmoun, who is already fifth on Iran’s list of all-time leading goalscorers after taking his tally to 23 in 31 games during a 2-1 friendly win over Algeria in March.
The 23-year-old has also impressed for Rubin Kazan and Rostov in Russia and was linked with moves to Celtic and Everton last summer.
Veteran defender Jalal Hosseini has well over 100 caps, while Greece-based midfield duo Ehsan Hajsafi and Masoud Shojaei provide more experience.
Up front, Olympiacos forward Karim Ansarifard and Heerenveen striker Reza Ghoochannejhad are both coming off good club campaigns.
