Arsenal ace Eduardo admits he's upset over Croatia's failed World Cup qualifying campaign.

Eduardo admitted the disappointment of failing to reach South Africa still does not sit right.

"There were a few games in which we didn't play well," he said. "We have caused surprises in a lot of major tournaments in recent years, so this was very disappointing for us.

"There are a lot of good players in our team and maybe we could have done something in South Africa, but it is difficult for a country like Croatia to go to every single World Cup - we are not like Brazil, who never fail to qualify.

"We will learn from what has happened and put our efforts into preparing for the Euro 2012 qualifiers."
