Vedran Corluka has said that Croatia have "positive jitters" ahead of their opening match of the World Cup against Brazil.
Niko Kovac's side will face the host nation in the first game of the tournament following the opening ceremony on Thursday.
The defender told FourFourTwo.com: "We have positive jitters. We play the opening match with the host and there is no team that would not want to change with us.
"There are always desires and expectations, but we need to be realistic and say that we are in a tough group and we have the same opportunities as Cameroon and Mexico to reach the second round."
Croatia had to beat Iceland in a playoff to reach the finals.
