The US team has gone under 2.5 goals in both games played so far with a 1-1 draw vs Wales and a goalless draw against England. Not only that, they also have one of the lowest xG stats in the entire tournament so far generating just 1.42 expected goals in those two games played. Iran has also struggled in front of the goal with a 0.087 xG per shot tally, but unlike the Americans they were able to make the most out of their chances against Wales. Prior to the 2022 World Cup, the Iranians had 3 goals total at the 2014 and 2018 World Cups combined, plus they had scored 2 goals in a game only once in 9 outings in 2022 before scoring 4 goals vs England and Wales.
With their World Cup lives at stake here, I expect both managers to play more conservative here as nobody will want to risk this game getting out of hand. I was impressed with the US defense in the first two games, they held both England and Wales without a goal from open play. They have allowed more than 1 goal once in their past 9 matches, with 6 clean sheets in 14 qualifying matches. This game will not see more than 2 goals scored.
