ROSARIO, Argentina - Wallabies five-eighth Quade Cooper is warning there's no quick fix for his team's troubling form under new coach Ewen McKenzie.
Ahead of their final Rugby Championship clash with Argentina in Rosario on Saturday, Cooper predicted there could be more pain before any real gain.
The Australians suffered a disappointing 28-8 loss to South Africa, let down by turnovers and missed tackles at crucial times.
It will be no easy task to beat the Pumas on home turf after they pushed the world champion All Blacks for almost 60 minutes — leading early in the second half before a late 33-15 blowout.
Cooper was voted the Wallabies' players' player and worked hard in defence to stop the Springboks' onslaught.
He looked more at home in the second half with fellow Reds campaigner, halfback Will Genia, replacing Nic White.
He didn't want to use excuses about a new coach or injured players to explain their dip in form.
"We can't keep using excuses. We've run out of excuses as a team in terms of how we go about each week.
"We've just got to put it down to hard work, sticking together as a team, backing our coach, backing our players and we've got to strive for more success."
Cooper said there was a challenge issued to each player to improve on one thing each heading into the Argentine game, which they hoped would collectively make a difference.
"You have to look at yourself and find one thing in your game that you can work on, that you can contribute to the team, that will speed up the process of us improving as a team.
"We'll get there. It's all in due time but I urge everyone, it's not going to happen overnight.
"It's something that we've got to continue to be upbeat about but we've got to know that it's a tough process and it's something that will come but, right now, it's just not happening."
Cooper used Queensland's Super Rugby revival under McKenzie as proof that the coach was the right man for the job.
