England head coach Trevor Bayliss admits his team wasn't good enough in their 2-0 series defeat against Pakistan.
Pakistan thumped England by 127 runs in the third and final Test to take the series and with it rose to number two in the rankings, leaving England sliding to sixth.
Pakistan won the second Test in Dubai by 178 runs while the first Test ended in a draw in Abu Dhabi.
Asked about his reaction to the defeat on Friday, Bayliss replied: "It's obviously one of disappointment. The players, as well, at the moment are very disappointed - obviously knowing we had a chance to win probably three matches here.
"We were in all three with a chance of winning but in the end we weren't quite good enough."
England were deprived of a dramatic win in the first Test when light ended play with the tourists needing just 25 runs.
They then dismissed Pakistan for 378 and looked set for a good lead in Dubai before being bowled for 242.
England also had a 72-run first innings lead in the final Test in Sharjah before allowing Pakistan to set a 284-run target by dropping crucial catches.
Bayliss said there were mixed gains from the series.
"There are some positives ... but also some negatives.
"From a batting point of view, obviously the captain's (Alastair Cook) batting was superb, and so was (Joe) Root's," said Bayliss of Cook's 263 and Root's 85 in the first Test.
"But I think the younger, inexperienced batters all - probably bar Moeen (Ali), at the top of the order - spent some quality time in the middle, proving they can bat in these conditions for an amount of time.
"If you can do it once, you can do it again - and you can do it for longer."
