Aaron Mokoena is expecting a tough game for South Africa when they come up against Spain in their final Group A game.

The Bafana Bafana captain and his team are riding high after beating New Zealand 2-0 in their previous game, but still need a point in Bloemfontein to make certain of their qualification.

Bernard Parker was the hero against the All Whites, with his brace securing the win which lifted the host nation into second place on four points, two behind the Spaniards and three clear of Iraq.

Defender Mokoena warned of Spain: "They're a team packed with great players all over the field.

"We know it will be a difficult match for us, but I think it will be difficult for them too.

"We play similar football but they have the experience over us. However, in saying that, we will be very determined and will throw everything at them."

Defeat for Joel Santana's team at the Free State Stadium, coupled with an Iraqi win over New Zealand, would leave both teams on four points, meaning the final outcome could go down to goal difference, where the South Africans are currently ahead with plus two to minus one.

If the Asian champions fail to win, a draw or even defeat will be enough.

Parker, who was clearly the star man in the previous game, is confident they can qualify for the last four, adding: "Spain are the best team in the world, the European champions and the tournament favourites.

"We know they've got some big stars, but that's not going to make us nervous, anything but. We're going to raise our game and be even more confident. I'm sure we're going to do it."

Spain, who are expected to give several of their fringe players a chance, will be keen on winning and have two world-records in sight that are sure to act as further motivation.

La Roja will be looking for a 15th consecutive international victory after their win against Iraq moved them to 14 - the same number as Brazil, Australia and France - with the other incentive being a 35th match unbeaten.

The last time they lost was in November 2006 and if they avoid defeat, Vicente del Bosque's men will draw them level with Brazil, who set the mark between 1993 and 1996.

"Now that we've qualified it means that I can make some changes," the coach said. "But winning is still the most important thing, which is what we'll try to do.

"When things are going this well, you don't change the structure too much. We will give some different players a chance, but as I said, the priority is to win."

Asked whether he had a preferred team to play in the semi-final with Brazil, Italy and Egypt all in contention, he added: "It doesn't bother me. You have to respect all the teams and they'll all come with their own difficulties."

Group B will be decided on Sunday.
