On Kallis, Tendulkar said, "I first saw him in 1996. He looked an okay player and I thought, this guy could become a decent all-rounder. But over a period of time, how he changed his batting technique and worked on his bowling was incredible. "Kallis used to walk with his head down and I used to tell my teammates that once he has realised which way the blades of the grass are, he is going to make you pay."
