Ambati Rayudu's omission from India's World Cup squad after just three failures is "heartbreaking" but there should be no debate on Rishabh Pant's exclusion as he didn't grab his chances, feels former India opener Gautam Gambhir.

Veteran Dinesh Karthik being favoured over Pant has been roundly criticised with Sunil Gavaskar calling it a surprising move. But the hero of the 2007 World T20 and 2011 World Cup final said Rayudu not making the cut is the most unfortunate bit about the squad announced on Monday.
