Portugal just about made it to the last-16 of the World Cup where they will face Uruguay.
After an uninspiring 1-0 win over Morocco to put themselves in pole-position, Cristiano Ronaldo's side simply needed to avoid defeat vs Iran.
And things were going swimmingly after 45 minutes, with Ricardo Quaresma scoring one of the goals of the tournament.
His trivela was brilliant, but Ronaldo couldn't follow suit from the penalty spot, with Iran converting their own spot kick in injury-time.
The Asian outfit actually had a great chance to win right at the death, but Mehdi Teremi could only fight the side netting of Rui Patricio's goal.
Portugal finally prevailed, but footage from the game highlights just how lucky Ronaldo was in the final few seconds.
Real Madrid's talisman had already picked up his first yellow card for an elbow and just as Iran were trying to launch their last attack, he decided to act.

Iran players don't even react, which is weird...
But why hasn't this been talked about more? The BBC failed to mention it in their post-match analysis and it's hard to deny that Ronaldo should have been sent off.
His arms are in an unnatural position and the incident stopped Iran launching one more assault on Patricio's goal.
Just another reason for Iran and Carlos Queiroz to be angry with the final result.
The former Portugal manager did not hold back in his feelings towards Ronaldo about the elbow incident after the match.
He said: "The reality is you stop the game for VAR and there is an elbow. An elbow is a red card in the rules. The rules don't say if it is Messi or Ronaldo it's a little bit.
"Going back to the story about my daughter yesterday, I need to know if I am a grandfather or not. I don't want to know if my daughter is 'a little bit' pregnant or there is evidence.
"It is a red card. The question, for me, is not about the referees. It is about the attitude and the bravery and the character.
"The decisions must be clear for everybody, for the people. In my opinion, Mr Infantino and FIFA, VAR is not going well. That is the reality."
Imagine if he'd seen the handball as well...
