Ex-India bowling coach Bharat Arun said pacer Mohammed Siraj told him he will do whatever it takes to emulate Virat Kohli. "I think it was the hunger in Siraj...He had seen what Kohli has achieved," added Arun. "I told Siraj, 'If you want to be like Kohli, then like him, you'll have to sacrifice a lot of things'," he stated.
