What to look out for when India lock horns with South Africa?

I’m not going to go into detail about how Virat Kohli’s form has been or how well Dale Steyn has been bowling; instead, I go into the hard facts and look at players who could make an unexpected impact and what to expect and look out for when a resilient Proteas outfit play the in-form Indians in the second semi-final of the WC T20 in Dhaka. 

#1 Yuvraj Singh

The southpaw seems to have found his form when it matters the most. Yuvraj is known to be a big game player, and his form will have a huge impact on the match. He looked good but not at his best in the game against the Australians. This will definitely worry the South Africans. If Yuvraj finds his best form, even the likes of Steyn and Morne Morkel will struggle to keep him at bay. So the question is, has the sleeping lion woken up at the right time?
