The blaring vuvuzela trumpets and the dancing South African football fans will be partying all the way into the Confederations Cup semi-finals.

South Africa managed to advance to the next round despite losing to Group A winners Spain 2-0 in Bloemfontein because Iraq were a held to a 0-0 draw by New Zealand in Johannesburg.

Spain's win were their 15th in a row, and it was also the 35th straight game in which the European champions avoided defeat, equalling the record set by Brazil from 1993-96.

David Villa scored the first goal for Spain in the 52nd minute, only seconds after his penalty was saved by South Africa goalkeeper Itumeleng Khune, and Fernando Llorente added the second in the 72nd.

"The important thing is we go to the semi-finals," South Africa coach Joel Santana said. "It is important for the players. It is important for the people."

South Africa captain Aaron Mokoena took down Cesc Fabregas in the area to give away the penalty, and Villa stepped up to take it. But his shot was saved by a diving Khune, who then stopped a follow-up shot from Carles Puyol.

A minute later, however, Villa redeemed himself by scoring with his left foot and giving Spain a chance to break Brazil's 35-match unbeaten run with a victory in the semi-finals.

"They're not No. 1 in the world for nothing," South Africa midfielder Steven Pienaar said. "If you're not well organised, they can punish you and that's what happened today."

Most difficult game

Bernard Parker, who scored both goals against New Zealand, played alone up front and created little, but Pienaar and Teko Modise were able to keep the Spanish defence from getting too complacent with flanking runs up the wings.

"They made it very difficult for us," Fabregas said. "Of the three games, this was the most difficult. In football these days, you cannot let a team get on top of you. You have to dominate throughout the match and that's what we try to do."

The loss, however, didn't dampen the atmosphere at the Free State Stadium, where the crowd roared when the fans learned of the other result.

"The people have been unbelievable. It was marvellous support," Mokoena said. "I can only say thank you to fans. We cannot do it by ourselves. We need the support."

Both the Spanish and South Africans will have to wait to find out who they next face because nothing has been decided in Group B. On Sunday, Brazil face Italy needing only a draw to advance, while the world champions, Italy, can be eclipsed by both Egypt and the United States.

Spain will play in the first semi-final match against the Group B runners-up on Wednesday in Bloemfontein. The South Africans will face whomever win that group on Thursday in Johannesburg.

The final is set for June 28 in Johannesburg.

Failed to score a goal

Iraq, who held South Africa to a 0-0 draw in the tournament opener and just lost to Spain 1-0 in the second game, needed to win by two goals to have a realistic chance of advancing ahead of South Africa, but the Asian champions again failed to create much up front.

New Zealand, like Iraq, failed to score a goal in three matches in South Africa after surprisingly netting three in a 4-3 loss to Italy in a warm-up match.

After the match, New Zealand coach Ricki Herbert cheered his country's first-ever point at a FIFA competition.
