India's Kohli says fans should be 'measured' after World Cup woe

India captain Virat Kohli has urged frustrated fans in his cricket-crazy nation not to get emotional after their shock World Cup semi-final defeat to New Zealand on Wednesday.

Kohli's side went down to by 18 runs at Old Trafford after the last four tie was played over two days due rain in Manchester.

Chasing 240 for victory, India lost four of their top batsmen for 24 runs in the first 10 overs and were eventually bowled out for 221.

The unexpected loss left a largely Indian-dominated crowd at Old Trafford disappointed, while a billion fans back home tried to come to terms with the heartbreaking end of the team's bid for a third World Cup crown.

Indian cricket fans are known for angry outbursts after crushing defeats, but Kohli said losing is part and parcel of sport and should not trigger an extreme reaction from either supporters or players.

"I have always been of the favour of a measured reaction and yes disappointment is there in a loss but don't take it to extreme," Kohli told reporters.

"Because many players will not be able to process it. Everything has to be balanced, like we want it to be on the field.

"It is easy to criticise from the outside when somebody loses and you are put on top when are winning. But when it happens on a big scale then it is a national responsibility that how you react to the sport you watch."

Pre-tournament favourites India had topped the group table to book the semi-final clash with fourth-placed underdogs New Zealand.

But Kane Williamson's side posted 239-8 after batting first on a tricky pitch and then defended the total with some excellent fast bowling.

- 'Accept the failure' -

Kohli insisted the defeat, which came after India won seven of nine group games, will eventually be dissected to work out what went wrong.

"I don't think that I would like to break things down immediately," said Kohli.

"But in time we will have to sit down and analyse things that we could have done right in this game.

"We are not shying away from accepting that we did not stand up to the challenge and we were not good enough under pressure. Accept the failure as it shows on the scoreboard."

Kohli lauded Ravindra Jadeja's valiant knock of 77 that gave New Zealand a scare.

Jadeja put on 116 runs with MS Dhoni, who made 50, for the seventh wicket to raise hopes of a fightback, but the Black Caps held their nerve in the closing stages.

"In my watching Jadeja for 10 years, me playing with him as well, this is probably his top quality, like best knock according to me because the kind of pressure," Kohli said.

Kohli also quashed any knowledge of Dhoni potentially retiring, saying the veteran wicketkeeper-batsman has not spoken to him about his future plans.
