India will be playing three Twenty20s, five ODIs and four Test matches in the 72 day-long tour against South Africa.

The series will be starting in less than a month's time, and it is already making the former South Africa captain Graeme Smith "nervous."

Smith felt that the India tour will not be easy for the Proteas, as they will have to deal with the conditions and different wickets across the country.

This energy-sapping tour will require a lot of travelling and that should not make them lose their focus from the game. Smith also expressed that this will be an important tour for South Africa. If they manage to do well against India, then it will help them perform well against England as well, later this year.

"I'm a bit nervous. It's a tough tour for us and this is a big season for South African cricket with the Indian tour and the English tour later this year," Smith was quoted by the Times of India. "This could be the defining period for this team.

"Four Test matches in India are not going to be easy, especially because it involves a lot of travelling; a lot of people and the conditions are going to spin.

"I'm holding thumbs that everything will go well. If we have a good Indian tour, I think we'll then do very well against the English."

South Africa hold a brilliant recent record and that is what makes them the number one Test side in the world. Proteas have not lost a single Test series away from home since 2006. Smith helped South Africa draw two Test series in India back in 2008 and 2009.

"Our record of not losing a Test series away from home since 2006 has been incredible. Hopefully these guys will keep going and keep doing us proud," Smith added.
