They have a revered manager in Carlos Queiroz, who has previously taken Portugal and South Africa to the World Cup - as well as leading Iran to the 2014 tournament - and finished their qualification campaign undefeated as they cruised to Russia.

How They Qualified

There aren't enough superlatives to accurately describe the impressive fashion in which Iran qualified for this year's FIFA World Cup. Over their ten games in the final stage of the Asian qualifiers, they didn't once lose, and didn't even concede until the final fixture - twice to Syria in a 2-2 draw - by which point they had already mathematically qualified, having done so two games earlier.
The only side in the world to achieve a better qualifying record was Brazil. What's peculiar about the campaign is that they did it without scoring an impressive amount of goals - managing just ten goals as they won six and drew four of their qualifying fixtures.
Despite this, they harnessed the defensive rigidity that has characterised them under experienced coach Carlos Queiroz, easily finishing seven points clear of South Korea at the top of the group.
Group Stage Games
There will no doubt have been some wincing faces among the Iran faithful when their group was drawn. Any hopes they have of qualifying from the group stages for the first time in their history surely hinge on taking three points from their opening fixture against Morocco on the tournament's second match day; which will be no easy task in its own right.
Their other fixtures come against Spain on June 20 and Portugal on June 25 - two fixtures in which they will have to call upon all of the strength in defence which saw them qualify, and a large slice of luck, if they are to take anything.
Possible Route to the Final
Should Iran pull of the heist of the century and advance beyond the group stage ahead of - surely - either Spain or Portugal, they could well be rewarded with something of a winnable last 16 tie.
Well, at least in comparison to the gruelling Spain and Portugal games they'll have to survive to get there. If they get through, they will likely face the winners of group A, which consists of hosts Russia, Mohamed Salah's Egypt, Uruguay and Saudi Arabia. Even making it to this stage would be an immensely historic moment in Iranian football history, but you can't imagine them doing much beyond the last 16.
A potential quarter final would see them against either France or Croatia unless we see a bizarre turn of events elsewhere.
Iran have announced a provisional 24 man squad for the upcoming World Cup.

Iran are the weakest team in the group and will probably find it hard to take points from the two European powerhouses. Their hopes will lie on the“Iranian Messi”Azmoun.

What separates Iran from most of the other 'underdog' sides that show up at the World Cup full of confidence only to take one point from their group and finish rock bottom, is that Iran are a very solid unit defensively and after their qualifying campaign, will fancy themselves to keep a clean sheet against just about anyone.
Having said that, while they are an impressive side defensively, the quality possessed by Portugal and Spain means that to stand a realistic chance of qualifying, they will have to at some point step out and try and score goals.
As such, they will be relying on one of Reza Ghoochannejhad or Sardar Azmoun to replicate Iranian legend Ali Daei and get amongst the goals. Confidence and defensive rigidity aside, though, it's not likely that Iran will qualify. In addition to calling upon the performances of their lives, they will need one of Portugal or Spain to have an absolute disaster. It's happened before, however, and nothing will stop this Iran side from dreaming.
Well, Cristiano Ronaldo might.
