Austria coach Josef Hickersberger is confident that his side can reach the quarter-finals at Euro 2008.
The tournament co-hosts were held to a 1-1 draw by Nigeria in a friendly last week before they earned a morale-boosting 5-1 victory over Malta.
Hickersberger has kept his plans secret and has yet to reveal whether Alex Manninger or Jurgen Macho will be his first-choice goalkeeper.
He wants his players to keep fighting for places but expects to make an announcement on the goalkeeping position on Wednesday, just three days before the start of the competition.
"Of course I have a team in my head which will play against Croatia but I want to wait and use these remaining training days because I know all the players will want to show their best," Hickersberger told reporters at the team's base in Stegersbach.
Austria begin their campaign in Vienna on Sunday against Croatia with many experts writing off their chances of progressing from a group that also includes Germany and Poland.
Austria are the lowest ranked team in the tournament at 101st in the world but Hickersberger is hoping to spring a surprise or two.
He said: "We have set ourselves a big goal. We want to reach the quarter-finals and in the last days I have become more optimistic.
"We don't need to go to the betting shop to know our rivals are all favoured ahead of us. However, we have the home advantage and we have a chance of getting points."
Hickersberger admitted that Austria would ideally like to face their final Group B opponents Germany with four points from their first two games, but he dismissed suggestions that his side had a weakness in defence.
"I know it was not ideal that we let Malta and Nigeria score goals but this happens to teams like Germany too. We will work on it," he added.
