Jasprit Bumrah insisted it was a case of practice makes perfect as he secured India's place in the World Cup semi-finals.
India booked their last-four spot with a 28-run victory over Bangladesh at Edgbaston, a result which ended their Asian neighbours' hopes of making the semi-finals.
But Bangladesh were still in with a shout of a shock win until Bumrah – whose four victims were all clean bowled – shrugged off a damaged shoulder to wrap up victory with two perfect yorkers.
"It's (down to) a lot of preparation," said Bumrah, who had injured his shoulder and spent time off the field after attempting to save runs on the boundary.
"Whenever I practice in the nets, I practice each and every situation.
"Be it with the new ball, be it with the old ball, bowling at the death.
"So if I've ticked all of the boxes in the nets, and in the match it's all about execution and keeping a clear head.
"If the work ethic is good, I think the execution feels much more easier in the game."
India reached 314 for nine on the same pitch that England had beaten them on only two days earlier to administer a first defeat in the competition.
But it seemed as if it would be so much better for much of the innings, with Rohit Sharma (104) scoring his fourth hundred at this World Cup and sharing a tournament-best opening stand of 180 with KL Rahul (77).
"We thought that the wicket will get slower as the innings progresses," said Bumrah, who was adamant he did not want to be rested for the final group game against Sri Lanka at Headingley on Saturday.
"So we thought that they'll come hard with the new ball, which they were trying to do.
"Our main focus was to get the ball as old as soon as possible, so our spinner (Yuzvendra Chahal) and our slower balls would come into play.
"That was the plan and that could be the nature of the wickets going forward.
"The summer is coming now, so the wickets could get drier. It was good practice for us."
Bangladesh coach Steve Rhodes said he was proud of his team's World Cup performances after being eliminated ahead of their final game against Pakistan.
"We've only picked up the three victories, but we've pushed a lot of these big teams throughout the competition," Rhodes said.
"With a little bit of luck, we may well have been one of these top four.
"I think we are the 'people's team' because of the way we've played against some of the big teams."
Rhodes felt the toss was crucial, providing India with a 20 to 30-run advantage in batting first.
"You saw that in the England match, that the cutters and the slower balls were quite difficult," said Rhodes.
"The wicket obviously proved to be a little bit more difficult in the second innings, but I thought we did fantastically well after that opening blitz by Rohit.
"It could well have been 370, 380, even 400 at one stage. So we were delighted that we showed a lot of spirit and a lot of fight to come back.
"To beat India, you've got to play at your best, and we weren't there in that first hour."
