Paul Farbrace, the England assistant coach, has said it is not enough for the team to purely see the one-day series against Pakistan as a learning experience and insists they have to gain positive results in order to develop.

England were comprehensively outplayed in the first ODI as Pakistan cantered to a six-wicket victory, which followed on from the 2-0 series defeat in the Test series. There has been a considerable change in personnel for the one-dayers - only five of the team played in the Test matches - and the bowling attack, especially, is raw.

David Willey and Reece Topley, who shared the new ball on Wednesday, have nine ODIs between them while in total the five main bowlers total 92 caps but Farbrace does not want any excuses.

"We're not here to develop and learn and go away and say 'well, we didn't win the series, but we're learning'," he said. "That's not what we want. We want to win - and it's really important we do."

"We have a group that need to learn quickly. We've said many times it's not about developing - we can't keep talking about that - it's about winning. That's the bottom line. It's up to the guys here to show they deserve to be in the side, for the long term, take the opportunities - but win at the same time.''

Someone who Farbrace can see learning quickly is Topley who claimed 3 for 26 in the opening match to briefly give England hope that their 216 could be competitive. He swung the new ball to trap Azhar Ali and Bilal Asif lbw then had Younis Khan caught at mid-on in his final ODI.

Topley has made a strong impression on Farbrace and head coach Trevor Bayliss since he was called up as a net bowler during the one-day series against New Zealand earlier this year and then promoted to the T20 squad on the back of his performances in training.

He made his T20 debut against Australia in Cardiff where he showed nerve in the closing overs to help close out victory and his scalps in Abu Dhabi opened his ODI wicket tally after a wicketless debut at Old Trafford in September.

"He showed, despite losing his run-up a couple of times, he got the ball up and swung it and took wickets," Farbrace said. "He's got the guts to bowl slower balls early on. He's got the skills, can bowl over and round the wicket, out of the back of the hand, cutters - and that's very unique to see a young bloke come in and actually have a very clear plan of how he wants to bowl. That's brilliant.''
