Sunil Gavaskar says he would only need "about 20 minutes" to tell former India captain Virat Kohli how he can come out of his slump.

Kohli has not made an international century since he reached three figures in a Test against Bangladesh in November 2019.

The 33-year-old endured a miserable tour of England, scoring only 31 runs combined in his two innings of the rearranged final Test at Edgbaston before failing to make it to 20 in his four white-ball knocks against Jos Buttler's side.

Kohli has been rested for the white-ball tour of the Caribbean and there have been calls for one of India's greatest batters to be dropped.

India legend Gavaskar would welcome the chance to help the country's former skipper to turn his fortunes around.

"Having been an opening batter, having been troubled by that line, there are certain things that you try and do." Gavaskar told India Today.

"It goes back to the fact that his first mistake turns out to be his last.

"Again, just because he is not amongst the runs, there is this anxiety to play at every delivery because that is what batters feel, they have got to score.

"You look to play at deliveries that you otherwise won't. But he has gotten out to good deliveries as well on this particular tour."

Gavaskar added: "If I had about 20 minutes with him, I would be able to tell him the things he might have to do.

"It might help him, I am not saying it will help him, but it could, particularly with regards to that off-stump line."
