England was "extremely poor" in the loss to Sri Lanka in the fifth ODI, according to their captain, Eoin Morgan.
But while Morgan, who was left for the game, England could take a look at Sam Curran, who also described his team's attitude as "very poor", felt that the overall experience could be beneficial for the team that is ahead of the World Cup campaign.
He promised that there would be "no paperwork over the cracks" when they reviewed what went wrong, having lost by a record margin of 219 careers in the Duckworth-Lewis-Stern method.
"It can be extremely useful," said Morgan. "During 50 passes today we were under a lot of pressure and we did not have many answers, that gives us a good opportunity to come back and see everything from the preparation to the final result, which is always better when you have been under a lot of pressure."
"Today we have not advanced in our game. There were areas where he went backwards. Our field was extremely poor, our attitude was very poor and that must be addressed. We will have to break down everything from yesterday's practice. Did we do too much the day before the game? Have we cooked too much? We could have been a bit fatigued. I do not know.
"We will break it down and find an answer because, otherwise, we will only be hiding the cracks, which is not what we want to do".
Sri Lanka reached 366, its highest ODI scoring against England – in the opening innings of the game, looting a bowling attack that included Sam and Tom Curran for the first time in an international game.
But Morgan defended the changes that England made in their lineup on the field that some of these players, especially Sam Curran, could enter the World Cup team as replacements for injuries.
"Sam has only played his second ODI today" Morgan said "If we are going to take it seriously consider it as a possible replacement if David Willey is injured for the team of the World Cup, we need to know more about him.
"Today we learned more about him. If Sam Curran's name appears on that paper, we know what his strengths and weaknesses are now, and we try to improve them as we go forward. You need games under your belt.
"When you stay out, the only thing you do not want to compromise is to win the game, that's the best environment to learn, but on the other hand, you want to see the players who come to be challenged and put under pressure. it's something we definitely saw today.
"People will say you do not want to see your players attack everywhere, hit them back in the head, but I think it's necessary to learn. When we go to the World Cup and play against the best teams that perform that way on a regular basis.
"It's not that you want to get used to it but that you want to get used to the situation and experience a refocus for the next installment."
However, the time for experimentation is over. England has only two full ODI series to play before embarking on its World Cup campaign, against the West Indies in the Caribbean and at home against Pakistan, and has to select its team before meeting with Pakistan in May.
"Today we played five games – and out of the batters," Morgan said. "Normally we played six, but the team's balance changed. I would like to think that we will return to our strongest suit and the strongest balance that will go to the West Indies and then to Pakistan and Ireland in the World Cup year. "
