The scoreless draw, the first of the tournament so far, helps Mexico stretch their unbeaten run to 21 games and Ricardo Lavolpe's team progress into the last four as group winners ahead of Brazil, who face Germany in the semis after drawing 2-2 with Japan.

Mexico won the competition in their homeland back in 1999 and if they can continue their unbeaten run for two more games the trophy will be theirs again.

For European champions Greece a solitary point is scant reward from this competition and the fact that they failed to score in three group games leaves German manager Otto Rehhagel with a lot of thinking to do.

"It goes without saying that we wanted to be more successful," said Rehhagel. "We obviously have a problem in attack as we have not scored for five games and you can not win games without scoring."

Greece must now concentrate on qualifying for the World Cup in 12 months time and they face a real struggle, currently lying third in their group, eight points behind Ukraine and one point adrift of Turkey.

"I hope to get some of our top players back and maybe they can make the difference and help us qualify for the World Cup," Rehhagel declared.
