India's assistant coach has said that the defending T20 World Cup champions will require "two big performances" in order to qualify for the semi-finals after their crash to South Africa on Sunday. India were red-hot favourites on home soil heading into the T20 World Cup but suffered a crushing 76-run defeat in the Super Eights, as the 80,000 fans at the sprawling Narendra Modi stadium fell silent. In their first run chase of the tournament, India's batsmen fell way short against some disciplined South Africa bowling.
