Chipperfield, who turns 35 in December and is a veteran of 66 caps since making his national debut in 1998, is one of a host of ageing Socceroos expected to call time on his international career after this World Cup.

After a disappointing performance in the opening game against Germany, when he was repeatedly exposed by the pace, skill and trickery of the three-time champion, Chipperfield is under pressure to keep his spot in the team with the younger David Carney pressing hard to take his place at left-back.

And if Australia is eliminated by losing to Ghana on Saturday night, Chipperfield knows it could be his last international game given there would be not much point in then playing him in a 'dead rubber' game against Serbia in the Socceroos' final group game.

However Chipperfield said even if the worst happens on Saturday and the Socceroos are beaten and he again performs poorly, he will still look back on his career with great pride.

"I have had a great career and I am happy with what I have achieved and whether I have a good or bad game on Saturday night (against Ghana) it's irrespective to me," he said.

"But I'd like to have a good World Cup and go out on a good note."

Chipperfield said he was not the only player whose spot in the side was under pressure following the 4-0 loss to Germany.

"All spots (in the side) are under pressure," he said.

"It wasn't a good performance so I don't think anyone could put their hand up and say 'I was happy with my game' so I think everyone in the starting team is under pressure."

Chipperfield said it would be the ultimate test of character for the Socceroos in terms of how they respond to one of their worst-ever defeats, against Ghana on Saturday, knowing that even a draw will almost certainly not be enough to see them progress to the knockout stages for the second World Cup in succession.

"It's a tough group but hopefully we can bounce back," he said.

"That is your job (to rebound from heavy defeats) and there are still two games to go.

"Everyone can have bad days but it's how you bounce back from bad days that determines if you are a good team or not."

While Chipperfield admitted the back four he was part of against Germany struggled, he said there were mitigating circumstances which made it difficult for skipper Lucas Neill, fellow 34-year-old Craig Moore, Luke Wilkshire and himself to keep the Germans at bay.

"We (the defence) probably played a little too high a line (as the Germans continually beat the Socceroos' off-side trap) but the main thing was they had time and space in midfield to play the balls in behind us," he said.

"For me personally sometimes I had two or three players to deal with and it makes you look bad at times.

"But there is not much you can do (in that situation) - you can only do your best and if that is good enough well it's good enough but if it's not, it's not."
