High stakes for hopefuls
Matchday 4 could go a long way to determining which sides reach the quarter-finals and which go home early. FIFA.com looks ahead to four high-stake matches.
The big match
Spain-Mexico, 14.45 (local time)
Spain were the overwhelming favourites going into their Rio de Janeiro 2007 quarter-final with Mexico, but this will not be the case when they meet in Marseille. Ramon Raya's side upset the Iberians on the Copacabana en route to the silver medal, and their Ricardo Villalobos-inspired come-from-behind victory over Japan on Friday relieved some of the pressure from their shoulders. The Spanish, by contrast, know that defeat would likely condemn them to elimination, and will be hoping Amarelle can propel them to a victory which would place them in the driving seat to reach the last eight.
The other games
The Brazilian fans will demand a breathtaking performance and another three points from their heroes against Japan, who face an uphill struggle to remain in the competition. Group C could have a different complexion to it by Sunday evening, with the top two and the bottom two squaring off. The losers of the Cameroon-Russia match would effectively be eliminated, while the winners of the Argentina-United Arab Emirates game will place one foot in the second phase.
Players to watch
They both scored trebles on their Marseille 2008 debuts, but will Argentina's Federico Hilaire or Bahkit Alabadla leave Prado beach smiling on Sunday?
What they said
"It's never easy to play for Brazil because every team wants to beat us. But we're not afraid by anyone and we definitely want to be there till the end. Especially because we love the atmosphere here in Marseille," Benjamin, Brazil player.
