Rahul, 27, has overcome probably the toughest phase in his life and career which saw him endure a dismal run in the Test tour of Australia and an interim BCCI suspension for making sexist comments on a TV chat show alongside India teammate Hardik Pandya.
Having put that phase behind, Rahul let his bat do the talking and alongside his Kings XI Punjab teammate Gayle, forged one of the most destructive opening combinations in the ongoing IPL.
"KL is definitely one of the players that comes to my mind (when you talk about the current India players), I hope he produces the goods like Virat. After Virat, it should be him," Gayle told PTI in an exclusive interview.
However, Gayle's advise for Rahul would be not taking undue pressure.
"But it is not necessary for him to put himself under that kind of pressure, he needs to be himself, stay in his zone and try not to compete with anyone.
"You have a lot of talent (in India), I could go on and on and most of them don't even get the opportunity (to play for the national team)," said the 39-year-old West Indian, who is in top form ahead of his fifth World Cup.
Both Rahul and Gayle have been the leading-run getters for Kings XI Punjab this season, having scored close to 450 runs in 11 games to warm up for the World Cup in near perfect fashion.
The Jamaican, who is into his second season with the franchise, has proved his detractors wrong time and again after being bought only for his base price in the auction before the 2018 edition.
Ahead of the 2019 IPL, he was in devastating touch in the home ODI series against England, smashing two hundreds and as many half-centuries in the five-match contest.
"Two years I have been here (with KXIP) and it has been phenomenal. I love the Punjab style. I am getting to work with a great bunch of people and hopefully, we can do something special for the franchise. The aim is get to the play-offs and take it from there."
He is also highly impressed by the work ethic of captain Ravichandran Ashwin, who has not played limited overs cricket for India in the past two years with wrist spinners taking centre stage.
"I don't know what happened there (why he is not in India's limited overs setup). He has been a phenomenal bowler for India. He is a very passionate bowler, equally passionate as captain and someone who strongly believes in his ability as well his team's. It is very good to see that in a captain," added Gayle.
