In one of the episodes of the show, Salman gave an earful to Kushal for insulting actress Tanisha Mukherjee last week.
Kohli took to micro blogging site Twitter and said that Salman firing Kushal was required.
"My last word on 'Bigg Boss - Saath 7' fight, Salman Khan firing Kushal (Tandon) so needed, he pulled up Tanisha (Mukherjee) too. Kushal a bad player. Now let's move on," Kohli tweeted.
