Ajinkya Rahane surely showing he's set for a long Test career. Whereas overrated players like Rohit and Pujara are hyped to the moon and back, Rahane just lets his bat do the talking. Rahane's already bagged a hundred @ Wellington, Lords and the MCG(plus a 96 at Jo'burg). Classy player.
Kohli has shown he had the capability to rectify the technical errors he made in the horror tour of England. In England he played with an open face too often, he's certainly fixed that in Australia. He's already got 6 Test hundreds outside Asia.
