What I loved about Karun was that he started from scratch after 100,then after 200 & if he had the chance would have done after 300 too.👏👏👏

Kohli, Ashwin & Karun are the first three names on the team-sheet for the next Test…I'm expecting team composition to change vs Bangladesh

Makes 303no in his third Test. Good eg why it's way too early to give up on Nic Maddinson #INDvENG
