"If we show what we can do, I know we can be among the top teams at this tournament," Aragones said. "I thought it was going to be more complicated, but the second goal made Ukraine more crestfallen and the rest was easier."

While the Spaniards are making their eighth consecutive World Cup appearance, they have failed to reach the semifinals since their best result, a fourth-place finish in 1950.

Xabi Alonso scored Spain's first goal in the 13th minute with a header past Oleksandr Shovkovskyi.

Villa made it 2-0 four minutes later with a deflected free kick, and then added another in the 47th from the penalty spot after Torres was brought down by Vladyslav Vashchyuk, who was ejected. It was the first penalty kick of the tournament.

"It's painful to lose 4-0," Ukraine coach Oleh Blokhin said. "I've never lost 4-0. The players did not respect the advice of their coaches. On some occasions, we were playing like the worst team in Europe."

Andriy Shevchenko, expected to shine on world soccer's biggest stage, had little effect. Blokhin had hesitated to start the striker, who was returning from a knee injury.

In Munich, Jaidi scored Tunisia's equalizer in injury time, heading in Ziad Jaziri's cross from 10 yards only minutes after Sami al-Jaber had given Saudi Arabia the lead.

Al-Jaber, a 34-year-old veteran, picked up a through ball and slotted it past Tunisia goalkeeper Ali Boumnijel with his first touch in the 84th minute. The Saudi player, who came on as a substitute in the 82nd minute, has scored in three World Cups.

Jaziri gave Tunisia the lead in the 23rd minute, but Yasser al-Qahtani tied it in the 57th.

Tunisia coach Roger Lemerre was disappointed his team couldn't hold on to the lead.

"We don't feel like we have opened the door," Lemerre said. "We weren't very assured. While the first goal gave us a boost, it was not enough."
