The first day of the first test match will be extremely crucial. If SA bat first and don't lose wickets, and look to set up a daunting total, all the momentum generated from the Aussie tour success would be left behind psychologically.
If India bats first and SA get 7-8 wickets DAY 1, India would lose the edge they are carrying with more expectations than ever. SA have little to lose, India on the other hand is tired from the Aussie tour.
First day extremely crucial. Hope India routs SA, inshallah :-)
