After edging the United States 2-1 in extra time on Tuesday, Belgium coach Marc Wilmots turned his attention to the tougher opponents Argentina which they will meet in the quarterfinals.

Wilmots said after the breathtaking duel that the U.S. match was nerve-wracking, but he is looking ahead to Belgium's next test.

"We've seen a very conquering Belgium team," Wilmots said. "(American keeper) Howard had a fantastic match. We deserve our win. We need to forget about this match. Four days is very short to prepare for the Argentina game."

Captain Vincent Kompany recovered from a groin injury in time to face the U.S., and Wilmots said Thomas Vermaelen and Steven Defour should both be fit to face Argentina as well.

"We will have Vermaelen and Defour back," Wilmots said. "They will be ready for Argentina."

Admitting that Argentina will be favored, Wilmots said that Belgium have the confidence to reach the semifinals.

Responding to a question about Argentina, Wilmots said, "There s a lack of balance in that team."

"We're going to make sure that we play well against a strong team, and every detail will make a difference. They play with five defenders, so we will have to be creative. I have everything in my head already, don't worry," he noted.
