Australia coach Pim Verbeek is not relaxing despite the side recording a 2-1 win over Oman on Saturday.

The win gave the Socceroos every chance of qualifying for the 2011 Asian Cup in Qatar with them needing just three points from their two final matches.

But Verbeek says it is important not to think they are over the line yet.

''We cannot relax, you can never relax. Once you have definitely qualified, that's when you can relax," said Verbeek.

The Socceroos made tough work of the win, coming from a goal down with ten men to finally reel in the plucky Omanis with Verbeek adding he thought the sending off of Middlesbrough's Rhys Williams was a touch harsh.

''The penalty was 100 per cent,'' Verbeek said. ''It was bad organisation from Rhys, and he knows it himself. He felt unhappy about it. But the red card, it was harsh. So we have to play 75 minutes with 10 men - we reorganised, we play man to man, we took some risks, and it paid off.''

But Verbeek also heaped praise on his players, saying to win an away game shows plenty of character.

''If you start winning away games, you can say it is a turning point," he added.

"We have now played two times against one of the better teams in the group, and we pick up six points. The result is fantastic, the spirit is fantastic. So we are very happy with this result.''
