Highlights: Ghana 1-2 USA

John Brooks headed a late winner for USA in a dramatic finale to their opening Group G game against Ghana.

Clint Dempsey put USA ahead on 29 seconds with the fifth-fastest goal in World Cup history, cutting inside John Boye before sweeping home.

Ghana upped the tempo and equalised when Andre Ayew latched on to Asamoah Gyan's backheel to fire in a leveller.

Analysis Thierry Henry New York Red Bulls striker "One of the moments of the World Cup for me was the reaction of John Brooks for the winning goal. That was priceless. That is what the World Cup is all about. "The way Ghana conceded the corner kick that led to the USA winner was poor. In these games, you can't do that. They are in trouble. They still have to play the big dogs in the group."

USA looked tired but Brooks nodded in from six yards following a corner to give his side a winning start.

Centre-back Brooks reacted with a mixture of disbelief and delight, the Germany-born 21-year-old marking his Fifa World Cup debut and fifth cap in style.

The victory also gave USA a measure of revenge for being knocked out of the past two World Cups by Ghana.

They had looked to be tiring, and a winner seemed unlikely as Ghana dominated the second half and pulled themselves level.

But their tenacity was rewarded to leave the Black Stars precariously placed, with both teams having to face Germany and Portugal.

Ghana exited the World Cup four years ago in tears, when Gyan's missed penalty in the last minute of extra-time against Uruguay denied them the chance to become the first African side to reach the semi-finals.

USA score after 29 seconds

If they were still nursing that pain, they did not show it as they sang and danced their way into the dressing room at the Estadio das Dunas.

But they fell behind within the first minute. Dempsey collected a Jermaine Jones pass on the left wing, cut inside right-back Boye and shot into the far corner.

Ghana struggled to mount a response as the USA consolidated their lead with a work-rate and organisation that kept their rivals at bay.

Indeed, Jurgen Klinsmann's side could, and maybe should, have extended their lead. Striker Jozy Altidore controlled a low, right-wing cross but his shot from 10 yards was blocked by Boye.

That was Altidore's last major act of the game, a hamstring injury seeing him replaced by Aron Johannsson.

Key facts Hertha Berlin's John Brooks was left out of a match against Bayer Leverkusen in April after a newly-inked tattoo caused him to miss training.

Clint Dempsey has scored in three successive World Cups, with two of his three goals coming against Ghana.

Ghana had 21 shots, a joint-high in the World Cup so far (along with Ivory Coast) but only three were on target.

USA scored more than once for only the third time in their past 12 World Cup games.

USA centre-back Matt Besler also left the field injured, and his exit, combined with Ghana increasing the pace of their play, resulted in the Black Stars piling the pressure on Tim Howard's goal.

Most of the chances fell to Gyan, but he nodded high from 10 yards when unmarked before having another header tipped wide by Howard.

Gyan may not have scored, but he set up his side's equaliser as his lovely backheel teed up Ayew to shoot home with the outside of his right foot.

It seemed Ghana might have enough time to engineer a winner, but Hertha Berlin defender Brooks had other ideas, and his first international goal following Graham Zusi's corner proved decisive.

Klinsmann has a 100% record in opening World Cup games

United States manager Jurgen Klinsmann:

"I said to the bench a few minutes before our winner, 'We are going to get some chances - we need to push and grind it out.' We trained over and over on set-pieces and it was well deserved.

"We have a great spirit and fight until the last minute. It was a grind but it was a wonderful one at the end of the day.

"There is stuff we need to improve. We had problems with keeping the ball."

Ghana coach Kwesi Appiah:

"What I can say is that it was a very tough game. Playing at this high level, any little mistake can cost you dearly.

"We didn't deserve the first goal against us and we did create a lot of chances.

"Unfortunately we could not take our chances and the US took theirs.

"Any loss of concentration can cost the team big time. I believe the first goal unsettled us a little bit but I never expected it to end this way."
