It would be bookable offence if India were to lose in England, Australia: Chappell

Australian cricket great Ian Chappell feels India losing back-to-back Test series -- in England and against a depleted side Down Under -- would be a "bookable offence".

Former captain Chappell also said the next few months will be a defining period in Virat Kohli's captaincy career.

Prior to reaching the UK, India had a glorious opportunity to defeat two heavyweights in England and Australia in consecutive away Test series. Had they done so, it would have been a laudable achievement," Chappell wrote in 'ESPNcricinfo'.

"Now Kohli's team are in danger of not only wilting tamely against England but also of providing a depleted Australian team with a confidence boost, to the point where they will feel their chances of victory at home have greatly improved.

"If India were to lose both series, it would be a bookable offence."
