Let’s put it another way.
In vs out
Bremer vs De Ligt
Gatti vs Chiellini
Di Maria vs Dybala
Pogba vs Ramsey
Paredes vs Arthur
Milik vs Morata
Kostic
Fagioli/ Miretti vs Zakaria
Almost all of these are upgrades, except maybe Gatti vs Chiellini (who has serious injury concerns at this point) and Milik vs Morata.
As for Tek and Sandro staying. Lord Tici gave them a fat contract, so moving them on is almost impossible.

Gatti vs Chiellini - Gatti is still unkown for me while its not exactly prime Chiellini
Di Maria vs Dybala - Di Maria is the better player but he came for one year while Dybala would have been more than just a one year deal.
Pogba vs Ramsey - Obviously Pogba
Paredes vs Arthur - Paredes would be better for us but Arthur might show some nice moves with Liverpool
Milik vs Morata - Morata
Kostic
Fagioli/ Miretti vs Zakaria - Miretti was here last year while Fagioli didnt get any minutes yet. Zakaria was mostly injured last season IIRC
