Iran vs USA - The most politically charged match of the World Cup is here

The United States and Iran, diplomatic rivals for more than 40 years, clash on the football pitch on Tuesday, their places at the World Cup on the line in a fitting finale for the most politically charged group at this year's tournament.

The national team coaches sidestepped the icy bilateral relations, saying they were focused on the tournament and its ability to bring people together.

Washington and Tehran severed diplomatic relations in 1980 after the Islamic revolution. Ties have been strained in recent years when then-President Donald Trump pulled the United States out of an Iran nuclear deal. The United States killed a top Iranian general in 2020 and Tehran responded with missile strikes at U.S. forces based in Iraq.

"I envision the game being hotly contested for the fact that both teams want to advance to the next round, not because of politics or because of relations between our countries," said U.S. coach Gregg Berhalter.

"The thing about soccer is you meet so many different people from all around the world, and you're united by a common love of the sport. We're soccer players and we're going to compete and they're going to compete and that's it."

Iran's dramatic 2-0 win over Wales and the U.S. team's tense goalless stalemate against England on Friday set up a tantalising final round of Group B matches.

England, sitting top with four points, face bottom side Wales, meaning the Iran-United States contest will decide which team goes through to the round of 16.

The eagerly awaited meeting is a rematch of the 1998 World Cup group stage contest, dubbed the "mother of all games", which Iran won 2-1. In a symbolic moment before that match at Lyon's Stade Gerland, the Iranian players gave white roses, a symbol of peace in the country, to their American opponents.

Overshadowing Iran's World Cup build-up this year has been civil unrest at home over the September death in police custody of 22-year-old Mahsa Amini, arrested for flouting the country's strict Islamic dress code.

Team Melli declined to sing Iran's national anthem in their first game against England in an apparent show of solidarity with protesters. They sang quietly on Friday at the Ahmad bin Ali Stadium, where boos and jeers were heard from Iran supporters.

Amid growing public pressure on players to take a stand over a deadly crackdown on protests, Iran rallied late against Wales to rescue a World Cup campaign that seemed to have flatlined following their 6-2 thrashing by England.

Berhalter, whose exuberant side drew 1-1 with Wales in their group opener, described the match as his team's "first knockout game" of the World Cup and was wary of the threat posed by Iran after their second-half assault against Wales.

"Now we need to be sure that we are good enough to go to the second round," Iran coach Carlos Queiroz said after his team kept alive their hopes of a first ever trip to the knockout stage.

"The U.S. is a brilliant team as well, as we saw them against Wales.

"Our preparation starts with a good rest, refresh the minds and put all the complementary and garbage things outside of our minds and focus on our goal, because what we want to do is to give this gift to Iranian fans."

Players to Watch

Iran: Sardar Azmoun

After being benched for the defeat to England, Azmoun started against Wales and carried real promise both in terms of his link-up play – their early disallowed goal was teed up by him – and his goalscoring threat.

His four shots was a team-high as was his 0.46 xG, he was just unfortunate in front of goal as he hit the post and saw a close-range header blocked by Wayne Hennessey.

Nevertheless, his performance was something of a statement after being left out on matchday one, and his pairing with Mehdi Taremi – who remarkably created eight chances last time out – will surely be key if Iran are to beat the USA.

USA: Christian Pulisic

The USA need to win, so they could do with their most-recognisable player leading by example in attack.

Pulisic had his moments against England, with his combined tally of five shots and chances created a high for his team, while he also generally worked hard, engaging in more duels (10) than any other USA player.

There's a perception Pulisic has failed to develop as many expected when he was younger, but this would be a great time to remind the doubters of his ability.

Prediction

According to Opta's prediction model, the USA are more than twice as likely to win this game than Iran are, with their respective victory chances at 50.2 per cent and 24.1 per cent.

In fact, the supercomputer reckons a draw (25.7 per cent) is more likely than an Iran win, though crucially for Carlos Queiroz's men, a stalemate could be enough for progress as long as Wales don't beat England.
