(CNN) -- Some of the world's top footballers remained eligible -- barely -- to compete in next year's World Cup after tense matches late Wednesday in Europe and South America.
The ultimate prize -- 32 teams will be bidding to raise the trophy in South Africa next year.
Top of the list is playmaker extraordinaire Lionel Messi, whose national team Argentina scraped a 1-0 win against Uruguay in Montevideo to secure the fourth automatic place from the South American group.
Fifth-placed Uruguay now face a November playoff against Costa Rica, the fourth-placed team from the CONCACAF group, to secure a spot in South Africa next year.
Portugal's Cristiano Ronaldo will also be hoping his team can qualify via the playoffs after they beat Malta 4-0 on Wednesday to seal second place in their European qualifying group.
With teams competing all around the world to ensure they will be in the hat when the draw is made in Cape Town on December 4, CNN gives you the lowdown on the current state of play following Wednesday's matches:
