This evening sees Spain take on Holland in a repeat of the World Cup final four years ago in South Africa. It is perhaps the best game in the first round of fixtures, and rightly so many are excited about the fixture.
Holland and Spain also have a tough group - the presence of Chile a scare for both of them - so victory in the opening game could prove paramount to qualification.
But there is of course plenty of Manchester United connections in this game. Firstly you have the manager of Holland. Louis van Gaal is to take over at Old Trafford after the tournament. Then there is the transfer targets - most of which will play for the Dutch this evening.
Then there is the players. Robin van Persie will lead the Dutch side, while Juan Mata and David de Gea are likely to watch from the bench this evening.
And it is the latter, the world champions third choice stopper in Brazil, who has been talking about facing RvP today.
"I've sent him the odd message. He's a great player and we'll have to follow him closely. I hope that he has a quiet game."
Luckily for De Gea it is not him who will be tasked with stopping the striker, but Iker Casillas instead - in surely the biggest game of the tournament so far.
