Not to sound cocky, but South Africa are a stupid chance of chasing this very large target down
If India could bat that well against the likes of Steyn, Philander and Kallis, then theres nothing in the pitch
Another factor: when South Africa chased down 434 against Australia in Perth, Australia was bowled out/ restricted and had no say or control of the target to set for South Africa as opposed to any declaration by the captain in control of the game
Possible the same thing has happened for India?
