Alastair Cook admits England fell short in three departments on the way to a 2-0 Test series defeat against Pakistan.
The world's best have all tried and failed to beat Pakistan in a 'home' series in the United Arab Emirates over the past five years.
For England, inexperienced spinners, all-too-familiar batting collapses and occasional lapses in the field all conspired in their downfall, with the third Test in Sharjah ending in defeat by 127 runs.
They are down to sixth in the International Cricket Council world rankings, with an equally daunting - if very different - challenge looming away to top-ranked South Africa.
Cook, whose own brilliant form at the top of the order continued, rightly exonerated his seam bowlers. James Anderson, especially, and Stuart Broad were hugely skilful and tireless - as was Mark Wood, who missed the third Test with a recurrence of his ankle problem.
Cook felt though that in other crucial areas England were outplayed.
He said: "We threw everything at Pakistan for 15 days, with our commitment, our thought, our desire - and in some really testing conditions.
"Our four seamers were outstanding, but the bottom line is we were just weren't good enough with the bat to repel the Pakistan bowlers at crucial times.
"Then with the ball and in the field, we weren't able to take those tough half-chances - in particular on Wednesday when the game was still alive."
Man of-the match Mohammad Hafeez rode his luck, in his second-innings 151.
"Hafeez has scored more than half their runs in that innings," said Cook.
"We had three or four chances to get him - none of them easy - but we weren't good enough to take them.
"I think that summed up the series. We were there or thereabouts but not quite good enough to put Pakistan under pressure or grab that opportunity ourselves."
England faltered at the final hurdle, set a target of 284 to win but mustering only 156 all out - despite Cook's 63 - after losing six wickets for 24 runs.
Perhaps the most jarring contrast of all, though, was how thoroughly Pakistan's spinners outbowled Moeen Ali, Adil Rashid and eventually Samit Patel.
"Out here you can see the damage their spinners did," added Cook.
"It's clear at the moment we haven't got world-class spinners - that's quite obvious to see.
"In India in 2012, we had two of the best spinners in the world and won the series pretty much because of Graeme Swann and Monty Panesar.
"We know there's an issue developing spinners at the moment in England, and I hope there's a real opportunity for people to push themselves forward in the future."
Cook unreservedly gave his team 10 for effort, on a tour which began in 40-degree heat and cooled off only marginally.
"I can't fault the lads' efforts. They've been absolutely outstanding," he said.
"But it's not down to effort. It's the crucial moments ... we have to front up to it and get better.
"We're an inconsistent side at the moment.
"I thought we played a bit more consistently here, even more so than in the (Ashes-winning) summer, but we just weren't quite good enough when it mattered."
Pakistan captain Misbah-ul-Haq warned before the series that England would be much tougher opponents than under Andrew Strauss in 2012.
In victory, he said: "England are one of the top teams, the way they have been playing after winning the Ashes.
"So winning against them is a big achievement, especially this time (because) they fought much harder than before.
"They are so disciplined, and don't give you any easy wickets or easy runs."
Like England, though, Pakistan must learn to win away too.
"I think our biggest challenge is to play abroad," added Misbah.
"We have to really get ready for that ... play differently, plan differently. If we are a very good team, we have to prove ourselves in foreign conditions."
Pakistan must venture to England next summer, by which time Misbah will be 42 - and he is equivocal about whether he will be staying on.
"I'm not sure about that. Obviously the hunger is there.
"I love the game ... (but) when you are not playing any competitive cricket for eight months and suddenly you come and play against top players, it's not easy."
