Ex-India cricketer Irfan Pathan has said KKR spinner Varun Chakaravarthy, who has played only three T20Is, could be a huge X-factor for India in the World Cup. "You have definitely played Chakaravarthy in the IPL...[but] it'll be different in the World Cup and the mystery will remain," Irfan stated. In IPL 2021, Varun has picked 10 wickets in eight games.
