After Virat Kohli edged a delivery to Australia wicketkeeper Alex Carey and got out in India's first innings at Gabba, Sunil Gavaskar said he needs to exercise restraint when it comes to playing cover drives. "He just needs to look at his hero Sachin Tendulkar's 241-run knock in 2004 in Sydney...wherein Sachin didn't play any shot in covers," he added.
