Former India head coach Ravi Shastri on Sunday said Virat Kohli's remarkable hundred is an "ominous" sign for Australia, and said no touring player in the last 15 years might not have produced such knocks more regularly than the batting star. Kohli brought all his technical expertise into play to score the 30th hundred on the third day of the first Test against Australia here, despite struggling for form in the run-up to the five-match Border-Gavaskar Trophy. This was 36-year-old Kohli's seventh century in Australia, the most by an Indian with one ahead of the legendary Sachin Tendulkar (6). Kohli's last century before this was the 121 against the West Indies at Port of Spain in July 2023, and since then 15 innings have passed without a three-figure mark. "Seven hundreds in Australia. The big stage, the big ground. One of the bounciest pitches in the world. I doubt an overseas player in the last 15 years has come to Australia and played in this fashion, Shastri said on Fox Cricket
