Jos Buttler believes England can put the ICC Cricket World Cup behind them by playing aggressively when they begin their five-match Royal London One-Day International series against New Zealand tomorrow.
England won just two games in the cricket showpiece whereas the Black Caps enjoyed a run to the final on home soil, where they were beaten by Australia.
With the side only scoring over 300 twice in their seven group games, wicketkeeper Buttler knows consistent high scores are needed if they are to challenge New Zealand in the upcoming series.
"You have to be brutally honest and say we were getting it wrong," the 24-year-old said.
"We almost had to play our perfect game to win. It's time to put the World Cup behind us. It was very disappointing but we learned some key messages.
"We have to be looking at scores of 350 and upward. That's the way the game's going. In a few years we'll look back at the World Cup and say it was a turning point in 50-over cricket.”
England were given a prime example of aggressive batting when Brendon McCullum scored 77 from 25 balls in the emphatic Black Caps victory during the dismal campaign.
And Buttler says it is vital to play without fear of failure to achieve the brand of cricket they need to challenge one of the best teams in the shortest format.
"The way (New Zealand's) Brendon McCullum captained, the way (South Africa's) AB De Villiers batted. This was a moment in time when the game changed and we have to follow that lead. We don't have any other choice." he said.
"We have to go out there with that freedom and no fear of failure and play the brand of cricket that is so accustomed to 50-over cricket these days. The talent is there.
"We've seen another side do this, so we can go in exactly the same direction as well.
"It gives the new players a real eye-opener as to what international 50-over cricket is now about. We want to win, but whatever happens it'll be a great learning curve."
Whilst England's squad has numerous changes, the Black Caps have a travelling party which closely resembles that which played in the World Cup.
Daniel Vettori might have moved on but 36-year-old Grant Elliott is still enjoying his cricket and will be looking to emulate his form which saw him score a match-winning 84* in the semi-final against South Africa.
"I am really enjoying pulling on the New Zealand shirt at the moment and like my role in the middle order where I could either be needed to score quick runs or rebuild after early wickets," he said.
"When you are playing for your country that is the pinnacle of your career and I am looking to prolong that by mostly playing white ball cricket.
"Our squad has had a few changes but the performances at Leicestershire show that the likes of Mitchell Santner and Ben Wheeler can do a job for us if they are needed.
"For Brendon it is all about making sure he has the right combinations in his team and it will be crucial when we turn up to Edgbaston that we assess the conditions and play the right team."
