Good play, nice intricate movement but when USA get themselves to the byeline, they make the wrong choice.

There's not been too much to get excited about so far. The Iranian fans to our left have been very loud throughout. The USA are starting to grow into it - they know they have to score.

Timothy Weah cuts a ball back into the mixer for the USA but it hits a couple of Iranian defenders and the Asian side clear their lines.

The Americans have certainly been the better team so far.

I thought the keeper was going to come. Good defending from Carter-Vickers but I thought Taremi was going to take a chance, maybe have a swing at it.

The USA are winless in their last five World Cup matches, since a 2-1 win against Ghana in the 2014 group stage.

Almost a good chance for Iran as Mehdi Taremi runs into the box onto a long ball but he doesn't shoot himself and tries to find Sardar Azmoun - but that pass is intercepted. Waste.

USA midfielder Weston McKennie dilly dallies too much on the ball instead of shooting when he gets it and he's tackled.

Exquisite cross, begging to be tapped home. Dest couldn't have done more than that. It was right in the corridor where you want it. One of the strikers had to do better and get on the end of that.

Lovely cross from Sergino Dest, not for the first time, but no Americans can take advantage in the box.

Dest is only 22 and has played for Ajax, Barcelona and Milan. Not bad football heritage.

The USA are pushing hard down the wings in the early 15 minutes or so, especially down the right.

Sardar Azmoun almost gets in for Iran onto a long ball but it runs to the US keeper. The US break but Weston McKennie can't find Timothy Weah.

As things stand USA would be eliminated without losing a game. They have to win.

The USA midfield three is one of the most athletic in the competition. They all have enthusiasm and they are quality players. We've seen some of the shocks in the tournament coming from workrate and those three have everything you need to dominate games.

Josh Sargent does well to keep a ball in play down the right and clips in a cross but nobody had kept up with him so Iran clear.

Yunus Musah played for England up to Under-18 level. He spent some of his childhood in England and was also eligible for Ghana and Italy.

Musah has started this game really confidently. He is capable of playing a pass and running past people. He is going to be crucial tonight if USA are going to get a victory.

The USA are starting to find their groove now. Yunus Musah puts in a lovely cross from the right and Christian Pulisic outjumps his defender but the header is straight at the keeper.

Not a bad strike from Musah, he took a touch and then hit it. He had to hit it straight away as the Iran defenders were coming out to him. Definitely worth an effort so early on in the game.

Sergino Dest crosses from deep for the USA and Alireza Beyranvand's punch isn't the most convincing. The USA keep the move going and Yunus Musah controls and volleys over from 20 yards.

USA's Christian Pulisic skips past Ramin Rezaeian, who brings him down. Free but no yellow.
