Both the teams have been undefeated in the tournament so far. Sixers defeated Chennai Super Kings (CSK) in their first match and making light work of the Yorkshire in their second outing to lead the points table on better net run rate.
Pacer Dirk Nannes was impressive for the Lions against MI but the bowler was taken to cleaners against Mahendra Singh Dhoni's side last night and Petersen would like him to come good against the Aussie outfit.
In left-armer Aaron Phangiso, Lions possess a quality spinner, who can see the side through the middle overs. But it will be a test for him to tackle the big hitting Aussie unit.
Experienced Niel McKenzie has held the middle-order well and with Gulam Bodi at the top also getting into runs column against CSK, the South African side has all the ingredients of a good unit.
