Melbourne, Feb 1: Cricket great Jeff Thomson has compared Australian bowling attack with a "third-grade club side," and said that South Africa will relish on the pace battery.

Thomson believes Australia will struggle to take the required 20 wickets to win a Test on their tour of South Africa, following Stuart Clark's injury setback on last Thursday,.

Thomson took particular aim at off-spinner Nathan Hauritz, tour hopeful Shaun Tait and spearhead Mitchell Johnson.
