Who will survive the World Cup hex?

The final round of CONCACAF qualifying for the 2010 World Cup gets underway this week but, despite plenty of familiar faces, the outcome is far from certain.

Mexico's recent troubles have led to serious concern south of the border that Sven-Goran Eriksson's side will struggle to book its place in South Africa.

The United States appears to be in good shape to go through due to its consistency and strength at home. Costa Rica and Honduras figure to put up a strong challenge.

Three teams go directly through to the finals, while the fourth-place finisher faces a playoff against a South American nation.

Below is a breakdown of the "Hexagonal" -- in order of predicted finish -- as the teams prepare for the 10 games that will shape their immediate World Cup futures.

1. United States

Bob Bradley's team may not be spectacular, but it knows how to win in this region and should have too much for its CONCACAF rivals. An opening victory over Mexico would be a perfect start on the road to South Africa, though doubts will remain about the team's ability to do well against more accomplished opponents on the biggest stage.

2. Costa Rica

The class team in the previous round of qualifying, Costa Rica won six games out of six and conceded just three goals. Los Ticos are well organized and efficient and won't fear anyone in the group as they look to reach their third World Cup in a row.

3. Mexico

Where to start with Mexico's problems? Head coach Eriksson's job is on the line before the Hex even starts after poor performances and his controversial insistence on selecting naturalized players. The team is packed with individual talent, but it is struggling to jell as a unit and looks increasingly susceptible on the road.

4. Honduras

Honduras clearly has the ability to match the top teams in the region on any given day, yet it must conquer its penchant for annoying slip-ups against weaker opposition. The emergence of Wilson Palacios in the English Premier League as a genuine star can only help Honduras' cause.

5. Trinidad and Tobago

The Caribbean nation was fortunate to reach this round, as it was helped by Guatemala's troubles and a victory over an under-strength U.S. side. An aging squad lacks real firepower, so it is hard to see the Soca Warriors gaining any results on the road. Fourth place could be the best T&T can hope for.

6. El Salvador

Two major problems face El Salvador -- a lack of discipline and a lack of talent. The weakest team in the group, it looks set to finish at the bottom. If the side fails to make an early impact, then expect a loss of morale and disruption of team unity.

So, will the U.S. have everything go its way or will CONCACAF spring some surprises? Share your thoughts and comments below.
