Haydn Gleed:, external I am very impressed by the USA in the World Cup. Should go to bed but enjoying the match.

Sherjeel:, external It's a shame USA have had injuries this match, with Jozy Altidore on they looked more of a threat and would have troubled Portugal.

"Fantastic save by Tim Howard. Ghana are winning all the second balls, the USA can't get out. The header was going wide but it was still a fantastic save."

This game has turned on its head. If the United States were cruising in the first half, they're hanging on now. Asamoah Gyan forces a finger-tip save from Tim Howard as the USA defence creaks. Kevin-Prince Boateng has now come on.

"Gyan was stretching but he'll be disappointed not to hit the target with that. Maybe it hit the 'three' on his head.

"Now Ghana are starting to dictate a little bit more. They're switching it from side to side rather than just attacking down the right."

"The game is crying out for Ghana's Kevin-Prince Boateng. When is Akwasi Appiah going to use him?"

Ghana manager James Kwesi Appiah has clearly rattled a few cages at half-time. Sulley Muntari goes close with a powerful drive before Asamoah Gyan heads a great chance over. Suddenly, Ghana have upped the tempo. The United States look rattled.

Ghana's lacklustre finishing continues. Christian Atsu wastes another opportunity after cutting inside and firing from the edge of the penalty area.

Miami Heat basketball player LeBron James returns to Facebook, external to root for the United States.

"Now that's how you start a match!! Clint Dempsey Goal!!!!" he wrote in his first posts after his social media absence for the playoffs.

Andy on text: With Portugal getting hit for four by Germany earlier and their goal difference suffering as a result, the winner of tonight's game will take a massive stride towards qualification. Maybe the pressure and importance of this match is getting to these two teams. It's been cagey stuff so far.

The United States have started the new half with a substitution, 21-year-old defender John Brooks replacing Matt Besler. Looks like a hamstring injury has done for him, Brooks slots into the centre of defence.

Following on from that, Ghana have out-passed the United States by a considerable margin. But can they make it count in the second half? The teams are back out.

Ghana might be creating few chances, but they are clearly targeting the right hand side as they look to haul themselves back into this, with 46% of their attacks coming down that flank, Christian Atsu at the heart of most of them.

"Clint Dempsey is so good at picking up these positions in behind and drifting over to the left. He's inventive. I was really pleased for him and you could see the joy in his face when he scored.

"It meant they could sit deep, use the two banks of four and other than that late chance, Ghana haven't created anything."

Despite trailing, Ghana have enjoyed 64% possession, while the United States have not had a shot on target since taking the lead. Funny old game, isn't it?

Clarence Seedorf
Match of the Day analyst

"It's played out so well for the USA. They had a really aggressive first minute but their organisation is spot on. It's going to be hard for Ghana in the second half."

Jason Roberts
Former Wigan, Blackburn and Reading footballer

"Ghana haven't created chances. The United States deserve the lead because they started so well.

"Ghana need more creativity. They haven't really come up with anything different and that's the challenge now. They haven't found that spark.

"The USA have got a good defensive record, they're a physical side, they're strong and they can keep clean sheets. They're doing a good job of defending this lead."

"I thought after the first goal we were going to have a crazy first half, but it wasn't to be. As we predicted though, the United States are a very organised side."
