Assistant coach Paul Farbrace has called on England to start demonstrating their ability to win matches as they prepare for their second one-day international against Pakistan on Saturday.
Ahead of the four-game series, captain Eoin Morgan had spoken about the need for the team to learn and develop during the clashes in United Arab Emirates.
Morgan made 76 in Wednesday's meeting in Abu Dhabi as England were bowled out for 216, with Pakistan securing a six-wicket win following a poor start which saw them at 14-3 inside just four overs.
England's batting let them down with several top-order failures as Pakistan moved into a 1-0 lead in the four-match series and Farbrace believes the tourists cannot be looking merely for minor improvements, with victory the sole target.
"With the one-day series, you know the games come thick and fast," he told ECB.co.uk.
"It's about the guys thinking about what they did and come back and give it a really good go.
"We think we have the ability and the players in our team to win this series.
"We're not here to develop and learn and go away and say: 'Well, we didn't win the series, but we're learning'.
"That's not what we want. We want to win - and it's really important we do. It is all channelled towards winning the next game.
"It's not about going from 220 to 250; it's about winning the game."
Pakistan's triumph ended a run of four straight ODI defeats at the Sheikh Zayed Stadium.
Mohammad Hafeez's century-making display stood in stark contrast to that of the England batsmen, but he will be under greater pressure with the announcement from Younis Khan that Wednesday's match would be his final international ODI outing.
Younis had been recalled to the team after being dropped following Pakistan's Cricket World Cup exit in March, but cut short his stay with the side after scoring just nine runs on Friday - Iftikhar Ahmed has been called as his replacement.
Hafeez has posted 100 twice in his last four ODI innings at this venue and is now Pakistan's third highest scorer of ODI centuries with 11.
