Dhoni led the Indian team to 2011 World Cup victory at home.
Sehwag revealed that Dhoni, who led the Indian team in that edition of the World Cup, only ate Khichdi as a superstition.
Sehwag shared the anecdotes while speaking on Star Sports after the ODI World Cup 2023 schedule announcement, citing that Dhoni's form with the bat wasn't the best for most part of the tournament but he continued with the superstition as India were winning their matches.
"Everyone was having some or the other superstition, and everyone was following theirs. MS Dhoni had a superstition of having 'khichdi' all through the World Cup," Sehwag stated.
"He used to say that even if I'm not scoring runs but this superstition is working, and we're winning matches," he added.
