Dhoni pinpoints what went wrong for India

India captain MS Dhoni believes two crucial no-balls and the dew that affected spin bowling contributed to his team's seven-wicket loss to the West Indies in the World20 semi-final on Thursday.

India had scored a highly-competitive 2-192 in Mumbai on the back of Virat Kohli's unbeaten 92, the No.3 batsman's third unbeaten half century in the tournament after his 55 against arch-rival Pakistan and 82 not out against Australia.

But the Windies punished India's bowlers in reply, Lendl Simmons' blistering unbeaten 82 off 51 balls well supported by Johnson Charles' 52 off 36 deliveries before Andre Russell smashed 43 off just 20 balls to help guide them to 3-196 and a thrilling win.

"When they started batting the first few overs were fine, but after that there was a considerable amount of dew which meant the spinners couldn't bowl how they would have liked to," Dhoni said after the match.

India had its moments to come back into the match; twice they got rid of Simmons, first when the right-hander was on 18 and then when he reached 50, only for replays to show the bowlers overstepping. 

"The only thing I'm disappointed about is the two no-balls," Dhoni said.

"I feel that the point at which the no-balls were bowled were quite crucial. If we had got those wickets, we would have got the opportunity to bowl at one or two overs of the spinners and get away with them without giving too many runs.

"A no-ball is something that can be avoided especially the front foot no-ball ... the only thing is that if you don't want to bowl a no-ball you should never bowl a no-ball."

Simmons, meanwhile, said India's lack of genuine pace bowlers helped the Windies in the run chase.

The Windies cautiously played out experienced quick Ashish Nehra (1-24) but smacked the two other young fast bowlers, Hardik Pandya (0-43) and Jasprit Bumrah (1-42) to fashion a victory.

And he admitted luck was on his side after twice been given a reprieve when the Indian bowlers over-stepped.

"Today was my day," he said. "Every cricketer has a day, today I had luck on my side and things went the way we wanted it."

"The (Indian) bowling was suspect, they had Nehra and Bumrah, the two fast bowlers but not express pace," Simmons said.

Simmons only flew into Mumbai on Tuesday after Andre Fletcher pulled a hamstring during West Indies' last group match against Afghanistan and was ruled out of the tournament.

"Before the game I felt a bit of pressure on myself, but it was good we had a target to chase and we got there," Simmons said.

"When I entered to bat I had a clear mind what I wanted to do because we already had a plan to chase the target."

Simmons said his two-year experience of playing for Mumbai Indians in the Indian Premier League was key in helping him to marshal the run-chase during which he decimated the Indian bowlers with his exquisite drives, pulls and cuts.

"Obviously it (IPL) has made me a better player, after playing IPL on these pitches you adjust to different strokes," he said.

"I was due to come to Mumbai on Friday and get ready for the IPL as well, see this is my home ground and I think I read it well."

Simmons set up the run-chase despite West Indies losing its swashbuckling opener Chris Gayle in only the second over.

He added 97 runs with Charles and then a quickfire 80 off just 39 balls with Russell to see his side through to Sunday's final against England at Kolkata.
