Full Story 10: Friedel saved a first half penalty from Lee Eul-yong and pulled off a string of superb stops in both halves to earn his side their fourth point in group D in front of a partisan crowd desperate to see a home victory.
Arena said: "Clearly, Friedel was the man of the match. There was a penalty, a call that we didn't quite see, but he came up with a big save. And he made lots of others."
He continued: "This was a big day for the people in Korea. In front of 60,000 people, under those [stifling] conditions that was a good result for our team. I'm going to take it and get out of town.
"They used their physical prowess and put a lot of balls in the box and put us under pressure. It was a completely different game to when we beat Portugal [3-2]."
