Away from family while grieving the recent loss of his father, India pacer Mohammed Siraj said skipper Virat Kohli's advice to be strong has helped him stay afloat as he gears up for a gruelling series against Australia.

Kohli is no stranger to overcoming personal tragedy while carrying on with professional duties. In 2007, Kohli lost his father in the middle of a Ranji Trophy match but he came back next day to score 97 for Delhi, showing his mental fortitude.
