The 32-year-old had announced last month that he would step down as captain of the Indian T20 after the World Cup and two days later he said that he will also leave the leadership at RCB after the current season.
“I would have to say and be honest, that in the one-day cricket and the T20 for the national team and the Royal Challengers Bangalore, he has come up very short,” Vaughan told ‘Cricbuzz’.
“The talent and squads he has to work with are up there with the best. RCB’s team over the years is very heavy on hitting.
“This year, with the quality of (Glenn) Maxwell and Harshal Patel and Chahal, they had the bowling alley to equalize the batting, and yet they have fallen short, “he added.
Kohli’s season as RCB skipper ended with a four-wicket loss to Horsemen of the Kolkata Knights in the Eliminator on Monday.
“His legacy as captain in IPL cricket would be one he did not win.”
“That’s what it’s all about. Top-level sport is about breaking the line, winning trophies, especially when you’re at Virat Kohli’s level.
“I’m certainly not saying he is, but he will see himself as a failure in the IPL captaincy because he is a very motivated player and person as he doesn’t have that trophy in his hands,” Vaughan added.
The former England captain added that Kohli is doing an excellent job leading the Indian Test team.
“In terms of what Virat is doing with the test team and the test match cricket, developing the Indian team, it’s fantastic.”
