Legendary para-athlete Devendra Jhajharia feels it`s a matter of time before star javelin thrower Neeraj Chopra breaches the elusive 90m mark while predicting that he can throw 93m in one or two years.

Chopra won a silver medal in the Paris Olympics with a throw of 89.45m earlier this month while the gold went to Pakistan`s Arshad Nadeem, who stunned the javelin world with an Olympic record effort of 92.97m.
