Jose Antonio Camacho believes his Spain team should have wrapped up victory over Ireland before the high-drama penalty shoot-out which took his side into the last eight.

The Spaniards needed all their reserves against the Republic of Ireland with Gaizka Mendieta knocking in the decisive spot-kick to give them a 3-2 win on penalties.

During the match itself, Robbie Keane rammed in a 90th-minute penalty to cancel out Fernando Morientes's eighth-minute opener.

"Although the Irish made lots of opportunities, we should have won earlier than a penalty shoot-out," said Camacho.

"We had lost of chances to decide the game, but we sufferd a lot tonight and we had to play a lot of extra time with only 10 players becasue we had injuries."

Keane's leveller came after Ian Harte had missed an earlier penalty, but Camacho disagreed with the second decision, awarded from a foul by captain Fernando Hierro on Niall Quinn.

"I do not think the last one was a penalty and the referee has not always decided for the Spanish side," he said.

Camacho had looked particularly nervous on the sidelines throughout the game, and he said: "It is a World Cup so the feelings are high."

Spain will now face the winners of Italy's match with Korea in the next round on Saturday.

"Italy have shown in past World Cups how strong they can be," he said.

"But Korea have big motivation to play us. They are playing in their own stadiums and intheir own country."
