Pochettino is just another puppet for this management IF he replaces Sarri which is highly unlikely. It would be the same issue, a manager stuck with the wrong players for his style.
The problem with Sarri is that he's just glad to be here and thankful for the opportunity. They don't respect his track record enough to meet his demands it seems like. We're stuck with these plusvalenza and freebie hit or miss transfers until a proven winner comes with specific demands for quality players. Then we'll see a Juve with a specific identity.
The thing for me is this:
I respect Sarri for thinking about modern football which means lots of one touch passes + applying pressure. The problem is that he does the right thing quite wrong.
The team is too slow on the offensive end (although we improved a bit).
We make the obvious and predictable moves which is also quite bad
The team is not defending well as a unit and the other teams are getting into the final 3rd quite easily.
The team seem like they dont have enough grit in their games.
The team take risks at wrong positions on the field.
On top of all that he seems to prefer "beauty" over effectiveness as I believe you can play a very beautiful style of football by playing to be efficient. We dont have to pick between the two.. We can choose both! and its definitely doable (Take a look at Bayern Munich, Liverpool and even Atalanta) (IMO Lazio played both a beautiful and effective style of football pre-Corona days)
Can he be the coach we need? I doubt it since its not just one thing that is problematic. Its too much to fix.
Pochettino - What I have seen from him - He prefers attacking style of football which is good. The teams he coached respected him which is also good BUT I dont consider him as a coach of the modern game.
The teams that succeed nowadays put pressure on opponents and play quick passes while dominating possession.
This is why in my books Pochettino shouldnt be considered as a replacement for Sarri but more someone like Gasperini. (We like them Italian anyway..)
Gasperini is not my no`1 choice but he seems like the best realistic choice.
