Chelsea defender David Luiz admits he's nervous ahead of Brazil 2014.
Home fans are putting huge pressure on the hosts to lift the trophy and the squad are feeling it.
"We are anxious, I wish it was starting tomorrow," said Luiz.
"Some nights we don't sleep. But that's all part and parcel. It is a great chance and we are privileged to play a World Cup in front of our own fans. I can't wait for it to start.
"Up to a certain point [anxiety] is good, it gets you thinking about the game. But too much is harmful so we'll have to work on that as a group."
