I don't know how to spend 800k in order to upgrade my team.

https://www.futbin.com/20/squad/10716187

Im playing mostly 4231 with Bernard st, Griezmann cam, Navas rcam and Lucas lcam.
I'm going to take Zanetti next week so RB is sorted for a while..
I have also Coutinho OTW (price dropped too much, my bad I should have sold him a few days ago) treatable, Politano Storyline, Vardy POTM.

At the moment my thoughts are:
A) Scream Insigne + Allan (replacing Lucas and Casemiro), plus Digne for chem and obv Politano for JNavas
B ) Dembele UCLL (worth 830k? Im worried about his stamina and strength) and maybe Joao Felix OTW per Lucas?
C) Mid ADP but this will take a lot, need half a mil
D ) Others .....

Appreciated any kind of help or suggestion
