The performances and results are two different spectrum. Psg result so far has been impressive, but their performances hasn't been that exceptional because of several factors that has mainly due with recruitment, injuries, and very little tactical (Messi not playing false 9, lack of interplay without Verratti in midfield(need to use wiljinaldum more), organization in defense). With regards to result, Pochettino is up there with tuchel and klopp. With regards to performances, Pochettino is below and alongside Nagelsmann, pep, ancelloti and simione. Once these issue that I stated above become settled, then psg performances will be as good as their result. Recruitment can't be fixed at the moment as they need better midfielders than Herrera and gueye(even though they have been good this season). Moreover, a quality number 9 like haaland, Kane, Lewandowski in replace of one of mbappe, Messi or neymar, unless Messi in the false no.9 works out, then a player like salah would be more ideal. However, once injuries and those minor tactical fixes are made then their performances will be as good as their result.
---------‐--------------Donamura
Marquinhos - Ramos/Diallo - Kimbemepe
Hakimi -- Verratti/Gueye - Wiljinaldum/Herrera - Mendes
--------------------------Messi(false 9) -------------
(Mbappe)Salah ------------------------------------ Neymar
That side seems much more balanced.
