That loss can be labelled as a 'fluke' instance because
1. They remained unbeaten in UAE over a series against any team they played against and that includes whitewashing England and Australia in UAE also.
2. Aside of the wins in UAE, they drew vs England in England over a course of 4- match test series and beat Sri Lanka and New Zealand in their own backyards too.
3. They didn't lost that series vs Zimbabwe so they actually managed to avoid the humiliation. Moreover, Misbah remained undefeated vs the Zimbabweans in that test, proving that he and Khan were the ones carrying the team for years.
In contrast, post the Mis-You retirement, Pakistan have lost home series to New Zealand and Sri Lanka and are yet to play vs England and Australia in those conditions, not to forget the losses in England and South Africa too.
Their newly founded girly love for Babar Azam seems to be overrated as he is basically nothing more than just a slightly better version of Manish Pandey ( who like Babar is also good vs pace and bounce but struggles vs spin) and playing in a weak team.
