India are grappling with a dilemma over who to select between the logical candidate or a sentimental favourite as the country's representative in men's 74kg freestyle wrestling at the Rio Olympics.

With the Wrestling Federation of India (WFI) also backing the 26-year-old, it seemed his place was certain until double Olympic medallist Sushil Kumar approached the Delhi High Court on Monday demanding a match between the pair to determine who should compete in Rio.

"Sushil has put forward his views before the committee and has maintained what he has been saying since the very beginning that he should get a chance to undergo a trial," WFI president Brij Bhushan Sharan Singh told reporters in New Delhi. "We have told him that 'you have put Indian wrestling at a pedestal and we cannot ignore your contribution and we all respect you'. But on the other hand, there is another wrestler who has brought the Olympic quota and also has been giving consistent performances. So, can we be unfair to him also?" Brij Bhushan added.
