Gambhir feels India should avoid 'blunder' by not selecting Ishan over Rahul in the ODI team."India will make a huge blunder if they don't play Ishan Kishan ahead of KL Rahul," Gambhir said in a chat on Star Sports.Gambhir explained his point, suggesting the consistency Ishan has shown over the last few ODI innings, be it as an opener or in the middle-order, warrants him a place in the team."The point is, when you're gearing up to win the World Cup, you don't see the name, you judge by their form. You choose the player who can perform and win you the World Cup," Gambhir said."I feel Ishan Kishan has done everything he needs to do to be a frontrunner," he explained.
