- The eagerly awaited clash is a repeat of the politically-charged 1998 World Cup game between the geopolitical foes, won 2-1 by Iran, dubbed the "Mother of all football matches."
United States coach Gregg Berhalter said politics would not come into his team's must-win World Cup clash with Iran following the Americans' battling draw with England on Friday.
Berhalter was a satisfied man after watching his youthful US team hold mighty England to a 0-0 draw at the Al Bayt Stadium in Group B.
The result sets up a tantalising clash with Iran next Tuesday when a victory for either side would guarantee a place in the last 16.

Berhalter however insisted that while tensions between the US and Iranian governments remain, politics would not enter Tuesday's occasion.
"I've played in three different countries, and I coached in Sweden, and 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," Berhalter said.
"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.
"We're soccer players and we're going to compete and they're going to compete and that's it."
Berhalter acknowledged however that the stakes for the game could not be higher, describing it as his team's "first knockout game" of the World Cup.
"We win or we’re out of the World Cup, and that's going to be the focus of ours in preparing the team," Berhalter said.
"But most of all we will need to understand the intensity Iran’s going to bring.
"We're going to have to be up for it if we want a chance to advance."
The USA are currently third in Group B with two points from two draws, trailing Iran in second, who reignited their campaign with a 2-0 win over Wales earlier Friday.
England, who lead the group with four points, face Wales in their final game.
That means that the US will secure a place in the knockout rounds if they beat Iran.
"Any time you're in a World Cup and you get to go into the last game controlling your destiny, that's a pretty good thing," Berhalter said.
Friday's composed US performance also carries the Americans further towards their goal of shifting global attitudes to soccer in the United States, where the NFL, basketball and baseball remain the dominant sports.
"We’re chipping away at it," Berhalter said. "You need games like tonight otherwise it's hard for people to get a good assessment of it.
"But we're not done, and we want to keep going."
US captain Tyler Adams meanwhile hailed the "next man up" doggedness of his team.
"Definitely would have preferred three points," Adams said. "But definitely happy with the performances of all the guys that performed tonight. It was that next man up mentality.
"Guys ran and competed until they couldn’t run any more.
"It's been a three-year journey full of ups and downs. But we can’t be too happy with ourselves – we’ve got to find the negatives and iron them out."
