Mickey Arthur has insisted his side would benefit from a 4-0 one-day series defeat by England as the World Cup starts later this month.
England, currently world's top-ranked ODI side, won the Sunday’s finale by 54 runs at Headingley as Pakistan's bowling and fielding let them down.
Arthur insisted he was in a much better mood now than he had been after Pakistan suffered a thumping 124 run defeat on the Duckworth/Lewis method by India in Birmingham at the 2017 Champions Trophy opener.
"We were beaten hands down at Edgbaston that day and I didn't really know where to turn because there wasn't a hell of a lot of positives out of that day," said Arthur.
"We sit here having taken a huge amount of positives out of this series.
"I thought our batting has gone to another level.
"People, coming to England, said we were a 280 team. We've dispelled that, that's given our batting unit a massive amount of confidence in the dressing room."
Moreover, Arthur was adamant the series against World Cup favourites England would help Pakistan.
"The other thing is we've played against a team who are number one in the world in their own conditions.
"I know there's not too many teams who will arrive in England as prepared as we are in terms of the competition we've played against and match-fitness," explained Arthur.
"All I know is the players are very determined to do well. Every time they go out there they play for 210 million people.
"We'll be ready -- come the first game against the West Indies, we'll be ready.
"I'm as confident we'll do well as I've ever been."
Pakistan's fielding looked to be improving when they were in England last year. However, in this series, Pakistan dropped simple catches and gave away plenty of runs with sloppy work in the outfield.
"It's been very disappointing," said Arthur, who insisted the decline in standards was not down to former Australia wicket-keeper Steve Rixon quitting as Pakistan's fielding coach in September over a pay dispute.
"That's a real worry for me because we are putting a hell of a lot of effort into it and there's not a massive amount of reward there at the moment.
"We'll just keep knocking away at it though.
"Fielding is about attitude and wanting to get out there and get it done.
"They (the players) know they've been short in this department and they are not happy about it. They are working damn hard at it."
