Trevor Bayliss wants to see England produce the "perfect game" as they go in search of glory at the World Twenty20.
England progressed to the semi-finals by seeing off defending champions Sri Lanka and will face New Zealand in Delhi on Wednesday.
Having started their Group 1 campaign with a defeat to West Indies, England also beat South Africa and Afghanistan on their way to sealing second spot, but head coach Bayliss feels they are yet to produce a complete display.
He said: "In these tight tournaments you can't get through to the semis unless you are playing good cricket and that's what we set out to do to give ourselves a chance.
"But it's about peaking at the right time. I wouldn't say we've played the perfect game yet - coaches are always looking for that absolutely perfect game, I don't think it's ever been played - but it's what any team is striving to do."
The match against Sri Lanka was effectively a quarter-final tie and Bayliss was heartened to see England cope well under pressure, which they also demonstrated after slumping to 57-6 before rallying to post a defendable total against Afghanistan.
"The more you are put in those pressure situations, the more you can win some of those matches," he said. "It makes the players into better players in the long term.
"Once you've been in those pressure situations, you can draw on those experiences from before. The game against Afghanistan, I mean, that was as big a pressure playing against them as it was playing against South Africa."
England won the tournament in 2010, when they were also beaten in their opening game by eventual group winners West Indies.
