Dries Mertens wastes a good free-kick for Belgium and then hits a poor cross. He has impressed at stages of the World Cup but that was not up to scratch. Kevin Mirallas could be an option out there on the right.

"You have to admire the USA's work ethic. The effort and desire to get back and make tackles, they do not hold back. And they do not strike you generally as being dirty, just strong."

DeAndre Yedlin whips in a great cross and Clint Dempsey attacks it but a Belgian head nips it away! There's goals in this. Trust me...

We've got a Mexican Wave in Salvador, but it's a much better game than that may suggest. After that wave of Belgian pressure it's the States who have control in midfield.

"Get Eden Hazard through the middle behind Divock Origi please Marc Wilmots..."

DeAndre Yedlin wins a corner with his first touch, great energy down the right. He plays for the Seattle Sounders by the way - anyone know what a Sounder is?

"This is the third or fourth USA player who has pulled up with a hamstring problem in this World Cup, and this is a real blow for them. Fabian Johnson, arguably their best player so far, was having some success against Jan Vertonghen."

Jurgen Klinsmann has to make a change as Fabian Johnson is replaced by 20-year-old DeAndre Yedlin.

That's not a typo by the way. DeAndre. The youth of today...

Calum Crowe:, external Belgium playing with much more freedom. Almost as if the pressure of failure is off after making it out the group.

Big problems for the USA as dynamic right-back Fabian Johnson pings a muscle and is down. The former Germany youth international will not run this one off. He's finished.

"The first 20 minutes were cagey but now it is open and it feels like a Belgium goal is coming. USA have to hold on because if they were to go a goal down it would be very hard to come back.

"We just saw the first piece of brilliance of the night from Eden Hazard. Belgium are moving the ball quickly which is exhausting for the opposition. Hard work for USA now but they don't mind that. They will work all night long."

"So much for the tight game we talked about. Both sides are having a real go and it's exactly what we wanted to see."

So open, end-to-end stuff, this is an antidote to the knockout stages so far.

Toby Alderweireld has to recover well to prevent Clint Dempsey from getting in and moments later Eden Hazard drills a shot at Tim Howard.

There's got to be goals in this one. Surely...

"When Marouane Fellaini is trying to get back into position, it is like he is in slow motion and he really needs to try hard to get back quicker.

"But that chance for Belgium's Kevin De Bruyne was the best chance of the game. He completely mis-hit it and a player of his quality, who was their top scorer in qualifying with the top number of assists, will be disappointed with that."

It's got to be! No!

Lovely stuff form Belgium though as they scythe through the US defence, Jan Vertonghen is in behind and does the right thing in drilling the ball across, but Divock Origi is crowded out.

Great stuff...

"Real belief from the USA, I think they had gone into their shells at the start of the game but they are beginning to come into it now. It's as if they have just been released. They are now going at full pace and both their full-backs are coming into it."

And now a great chance at the other end!

Belgium nick the ball back in the centre-circle and spring away, a three-on-two break. Jan Vertonghen is the legs through the middle, he finds Kevin De Bruyne on the overlap but from the moment he cuts inside on to his right foot the momentum is gone. The former Chelsea man gets a shot off but it's tame and wide.

Encouraging few minutes though. Both teams looking dangerous.

That state of national optimism will be continuing to grow as the US have a strong few minutes. Michael Bradley and Clint Dempsey combine superbly on the edge of the box and Dempsey tests Thibaut Courtois with a low shot from 18 yards.

The crowd are alive now. The men in white making all the running, pressing Belgium's players high up the pitch and forcing errors.
