Former India opener and two-time IPL champion skipper Gautam Gambhir feels Virat Kohli's non-performance as Royal Challengers Bangalore captain should lead to his removal from the hot seat as it is now a question of accountability. Known for his straight-talking, the hero of India's two World title triumphs made it clear that Kohli's name as a leader shouldn't be taken alongside the likes of Mahendra Singh Dhoni and Rohit Sharma, who are IPL's most successful captains. Asked if Kohli should be removed from RCB's captaincy, Gambhir said certainly, because the problem is about accountability.
