Painful and surprising to see Jitu not shooting great: Pavel Smirnov

India's pistol coach Pavel Smirnov, who once compared Jitu Rai to a diamond, struggles to comprehend how one of his most talented shooters slipped into oblivion.

Rai, who went into the 2016 Olympics as one of India's biggest medal hopefuls, suffered an inexplicable meltdown in Rio de Janeiro, to return empty-handed.

Quickly putting the disappointment behind, Rai found his bearing again and became the first Indian to win two medals in an ISSF World Cup the following year.

The Army man struck gold at the 2018 Commonwealth Games in Gold Coast and then came a lull that continues.

Pained at not seeing a talent as good as Rai in the thick of things, Smirnov thinks another shot at glory awaits the unassuming Nepali.

"It is painful to not see Jitu in action in international shooting. What happened I don't know," Sminov said on the sidelines of the ongoing season-opening ISSF World Cup in the capital.

"I was taking rest in Moscow for three months, so I was not with him, but it was surprising to see him not hitting the targets in the National Championships and the two selection trials," the Russian added.

Smirnov, who coached Vijay Kumar to a silver medal in 25m rapid fire pistol event at the 2012 London Olympics, is surprised at Rai's decline as he considers the Army man as one with the clearest of minds.

"He is very clear minded, maybe there could be some mistakes he is making while training, mistakes in preparation that are not helping him," Smirnov said.

"We have contact, but only live practice works, giving tips on skype, internet and over phone don't help."
