Socceroos boss Osieck labels Omani World Cup qualifiers is a must win
Holger Osieck has rated Australia's World Cup qualifier against Oman later this month as a must win affair.
The Socceroos host the Omanis in Sydney on March 26 needing a win to go clear of their opponents who sit on the same amount of points in Group B of Asian qualifying.
Osieck released his 23-man squad on Wednesday and is confident he has put together a group of players capable of pulling off a vital victory.
"The Oman match is a final and in a final you have to look at only one outcome and that is to win," Osieck said.
"There are no ifs and buts.
"We have put a lot of effort into this match and we want to win it and we will win it."
He added: "The match is crucial and decisive.
"We cannot afford to jeopardise anything. We have to go full speed and we have to win the game.
"I won't allow any discussion (on this subject). We have to be there and we have to win that game.
"This match will show down the road which direction we will take.
"I don't even want to think about the Japan game (in June). My focus is on Oman.
"It's a bumpy road and we have to be well prepared to get through."
