In his column for 'ESPNCricinfo', Chappell played down the role of a coach in any team.
"Kohli didn't have the same harmonious relationship with Anil Kumble that he enjoyed with Ravi Shastri when he was cricket director. The fact that India have now reverted to Shastri as coach prompts the question: 'Why change something that isn't broken?'," he asked.
Kumble resigned from the position after the Champions Trophy last month and admitted that his relationship with Kohli had become "untenable". Kohli, on his part, has not yet given any comment on the rift.
