Talking of Indian side, I feel return of Yusuf Pathan will boost the team because he is one player who can change the course of game within over or two but it is also an important series for Yusuf because this series will decide his future as a International cricketer. If he comes good I feel India will not feel the absence of Yuvraj Singh who is the match winner in one-day cricket for India. This series also give opportunity to Virat Kohli to prove that he can score runs against the best opposition and if he continue his form which he had shown against Lankans then I feel India will be difficult to beat. Another player who will be followed in this series is Sehwag, he is having fantastic record in test cricket but some how he is not that successful in one-day cricket, I feel if plays in one-day cricket like Test then he can produce many victories for India. he is one player who can crush any bowling side in the world, so he will be the key for India in this series. If he fails then India will lose this series.Another important aspect which gives advantage to South Africa is their fielding and that will make the difference, as we all know Indian fielding compared to South Africa is weak and lot will depend on the fielding and catching if India looks to win this series.
The way both team contested in Test Series I believe this will turn out to be cracker of the series. I feel at this moment its advantage South Africa purely because of their fielding and except Smith all their players are fit which is not the case with India.
