Kohli feels that now he knows "whom to trust" after the public outrage over his poor show against Australia in the semi-final of the World Cup. "To see those reactions after just one match was very disappointing for me personally. It makes you lose faith in a lot of people. It's a good thing in a way. You get to know who's with you and who's not. It was not in my control. But the reactions were very disappointing," Kohli said at the function where RCB announced its tie-up with home appliances brand Midea.
