They're not galacticos managers. They have spent money obviously, but they're not just getting the current best player in the world. They are buying players who will fit their systems (because they know what they're doing).
Here's a list of the top 20 players in the world at the moment according to goal.com

Mahrez
Bernardo Silva
Foden
De Bruyne
Van Dijk
Luis Diaz
Thiago
Alexander-Arnold
Mane
Salah
(Jota and Cancelo recently dropped off it.)
Half full of Man City/Liverpool players.
If not for Pep, would Bernardo Silva be that high? If not for Klopp, would Luis Diaz be that high? Those players are reaching their potential because of the managers, and Klopp and Pep are doing this every season.
To suggest that they couldn't do a better job than Dean Smith is just ridiculous
