"Don't Smile While Speaking": Virat Kohli's Fiery Command To Mohammed Siraj Over Interaction With Australians. Watch

Virat Kohli had a heated Day 1 of the fourth Test between India and Australia in Melbourne. With Australia beginning well, Kohli appeared more charged up to make a breakthrough. This not only led to a shoulder-barging clash with Australian opener Sam Konstas, but also a charged up comment to pacer Mohammed Siraj. As Siraj and Marnus Labuschagne were sharing a moment of banter, Virat Kohli was caught on the stump mic asking Siraj in Hindi to not smile while speaking to Labuschagne.

"Has ke baat nahi karna inse (We're not going to smile while talking to them)," Kohli could be heard telling Siraj as the fielders were switching across at the end of the over.
