An exasperated Mickey Arthur lamented Pakistan's failings in the field after their one-day international series defeat to Australia was confirmed courtesy of an 86-run loss in Sydney.
David Warner (130 off 119 balls) and Glenn Maxwell (78 off 44) starred with the bat as Australia racked up a mammoth total of 353-6 on Sunday.
Yet Warner, Maxwell, Steve Smith (49) and Travis Head (51) were all dropped during a dismal fielding performance from the tourists, who were subsequently limited to 267 all out.
"It's unacceptable," said Pakistan head coach Arthur. "Certainly, the standards we set for this cricket team haven't been met in the field. So that's really disappointing.
"[I'm] incredibly frustrated. And it's not through a lack of hard work; the guys have trained and trained and trained and somewhere between the training and going out on the ground, it's seemed to get lost.
"So we'll just keep pursuing that and keep endeavouring to get better and better because we have to.
"The gap between the best sides in the world and where we sit at the moment is not great in terms of batting and bowling, but in terms of fielding, athleticism, fitness, running between the wickets, the gap is massive.
"Batting and bowling, I can sit with and take some positives out of it. Fielding [was] woeful and way below standard.
"I said to the guys in our [pre-match] team meeting that I thought Australia were 15-20 runs better than us [in the field] - with bat or ball we can match them - and tonight they were 50 runs better. And you just can't compete [if that's the case]."
