The 2014 FIFA World Cup starts today!
The tournament takes place in Brazil from today, June 12 to July 13, 2014.

The first match is tonight at 9:00 pm (Swedish time) and it's Brazil against Croatia.
I don't know if it's a tradition that the host country gets to play in the first match or if it's just a coincidence (since they draw which teams/countries end up in which groups), but I think it's nice that they get to be in the first match and open the tournament since they're the host country.

I'll obviously watch the match tonight and I'm cheering for Brazil!

In 2014 FIFA World Cup I'm cheering for Spain, as I did in the World Cup 2010 and EURO 2012.
Spain is in Group B and they will play their first match tomorrow on June 13.

After Spain I'm cheering for Italy, which is my only heritage country that's in the World Cup this year.
