Why do you think the own goal happened? Why do you think the penalty happened? You realize you contradict yourself when you say no-one will remember Croatia and then ask how Iran's goals were scored! Its in the same line of thinking. Its the end day results that people will remember. Not how it happened.
At the end of the day Iran scored 2 goals. Which was 1 more than 2014, and 2006 and equal to 98 and 78. Keep in mind with tougher opponents and groups.
Why the own goal happened? I dont know luck ? Mistake by Moroccan defender?
Why the PK happened? mistake by the Ref? no ref in their right might would EVER give a PK for that ! and hence why he did not ref another game.
2014 Iran got 1 point, with 1 goal scored, Iran was in the same group as Argentina and Nigeria
- Argentina went on to finish runner ups
- Nigeria elimanted by France in Round of 16
2006 Iran got 1 point with 2 goals scored (not 1 as you have above) , same group with Portugal and Mexico
- Portugal went on to finish 4th
- Mexico eliminated by Argentina in Round of 16
1998 Iran got 3 points and scored 2 goals, same group as Germany and Yugoslavia
- Germany eliminated in Quarter finals by Croatia
- Yugoslavia eliminated in Round of 16 by Holland
1978 World cup Iran got 1 point with 2 goals scored, Same group as Peru and Holland
- Holland went on to finish runner ups

Now lets look at
2018 World Cup group

- Spain was eliminated in round of 16
- Portugal was eliminated in round of 16
Can you please tell me, based on what you think Iran had "tougher opponents and groups"
