Arena looks on in dejected fashion (Allsport).

United States captain Claudio Reyna believes his side deserved their place in the second round even though they lost 3-1 to Poland.

In the end the US clinched second spot in the group after South Korea beat Portugal 1-0 in Incheon.

"We have been a bit unlucky in the past but today we got our bit of luck," he said.

"Plenty of other teams went through with just four points so we will settle for that.

"Italy, one of the biggest teams in the world, needed luck to get through so we will take it. Overall I think we deserved our place."

However, the Sunderland midfielder was grateful for the contribution of the co-hosts.

"We are through tonight, not because we won, but because of what Korea did," he said.

"We owe them a big thanks. It was not a great way to go through, but we are through and that is what matters."

USA coach Bruce Arena said: "Nobody would have picked the results in this group, Poland played well but our guys never quit.

"The results throughout the tournament have been amazing, I would be crazy to dare pick a winner because there will be plenty more surprises to come. Who can believe the quality teams already at home.

"To go 2-0 down to a team of Poland's ability in such a short time, we knew it was going to be a battle," he said.

"But my players never gave up and I was pleased with that."

Penalty-saving goalkeeper Brad Friedel added: "On days like this it's better to be lucky.

"We didn't plan that first five minutes but you have to give Poland credit for a much better performance.

"I personally thought Portugal would beat Korea, but it didn't happen and we are through to play a country we know inside out.

"But please don't forget what a very great day this is for USA soccer and a very lucky day too."

The States face Mexico next in Jeonju on Monday, a team they have regularly beaten in the past, while Korea's debatable prize for finishing top is a reality check against Italy in Daejeon on Tuesday. You would not put money on the Koreans lasting longer now that the US!

Meanwhile Poland coach Jerzy Engel believed his players finally gave a true reflection of their ability after 2-0 and 4-0 defeats to South Korea and Portugal, respectively.

"My players showed that they belong at the World Cup," said Engel.

"For us, this game was very important because it was good for the mental state of the players.

"We represented our country and I was very proud. We won and leave with good memories."
