Melbourne: West Indies legend Vivian Richards has backed and lauded Indian Test captain Virat Kohli for his aggressive on-field attitude which has frustrated Australian cricketers during the ongoing four-match Test series.

Despite India trailing the series 0-2 after the first three Tests, Kohli is the second highest run-maker of the series with 499 runs from six innings which includes three centuries with a staggering average of 83.16.
