AB de Villiers
Playing against a South African side is always a tough ask. However, this Proteas unit is not as well balanced as it used to be over the years. However, they do have AB de Villiers in their ranks. With the bat the South African captain can change the course of any game, at any time, single-handedly. His captaincy was under the scanner after the initial setbacks against India and Pakistan, but now, after breaking the World Cup jinx, AB seems to have rejuvenated this Proteas unit.
Imran Tahir
South Africa have a fabulous pace attack with Dale Steyn, Morne Morkel and Kyle Abbott running in at 140 clicks an hour. But the Kiwis can handle pace and so can a few other teams. That's why this World Cup, their secret weapon has been a leggie. Imran Tahir has provided the Proteas with the edge that they have always lacked at major competitions for years. All this while, the Proteas used their spinners to stifle the runs but with Tahir, they are looking for wickets.
New Zealand's middle-order is a touch wobbly and is not known to be great players of wrist spin. Although, the smaller ground might go against him but Tahir has to be the key man for AB de Villiers if the Proteas want to brush aside this extremely efficient Kiwi unit to make it to their first World Cup final.
