The Reds will rely on Quade Cooper's audacious playmaking to revive their Super rugby defence against the Waratahs, but it's his improved defence that holds the key to his Wallabies return.
Cooper is likely to have tonight's crunch clash with the Waratahs, featuring Australia's incumbent first five-eighths Berrick Barnes at No12, as his last audition for a test recall.
The seventh-placed Reds need a four-try bonus point win to give them a realistic shot of making next week's playoffs, but national selectors will be looking at Cooper's tackling as much as the attacking skills that could keep the defending champions alive.
Reds coach Ewen McKenzie revealed he has returned Cooper from fullback to the frontline in defence to improve his claims on the Wallabies' No10 jersey for the Rugby Championship.
It's a challenge the 24-year-old, maligned as a poor defender since making his Reds debut in 2007, has embraced, but he is sure to be targeted by the Waratahs at Suncorp Stadium in Brisbane.
