Selling Bale and Kroos would bring in over 150 M $$ and Ronaldo to PSG also another 50. Our defence of Ramos,Pepe,Varane(+ Vallejo) is good enough and we are covered on the RB with Carvajal /Danilo. For defence the only thing needed is Marcelo backup,probably some young good talent who's at least better than Arbeloa. Moreno,Gaya,Rodriguez are among the more expensive options. Navas for DDG is optional but it wouldn't cost too much (for example selling Navas for 15-20 M then buying DDG for 40-50).
For MF we already have plenty of options (James,Isco,Modrić,Kovačić,Casemiro,Asensio) etc . We should still look for Tielmans/Verratti who are highly contested. Verratti will only work if we sell Ronaldo to PSG or if PSG buys Pogba or even both. I'd prefer Dybala for the RF position and if we sell Benzema then it's Aubameyang/Embolo or something. I'd sort it like this and I'm considering DDG a must because he's Spain's GK(our tradition).
Out: Navas - 15-20 M
Kroos - 50 M at least ?
Ronaldo - 50 at least
Bale - 80 at least - It'd probably be Navas 15,Kroos 60+,Ronaldo 70,Bale 100. We can get at least 250
In:
DDG - 50
Dybala Juventus singed him for 32,we could get him for 60 imo.
Verratti 80-100
LB backup . This would come around 230 if we pay 100 for Verratti and 20 M for a backup LB.
(optional) LW - Konoplyanka/Reus
Something like:
DDG
Carvajal-Varane-Ramos-Marcelo
James-Verratti/Casemiro-Modrić/Kovačić-Isco/LW
Dybala - Benzema/Aubameyang
It's obviously very hard to pull but we could manage without Verratti by fielding for example Casemiro-Modrić or Kovačić-Modrić. The main point is getting rid of Bale/Ronaldo or both if possible and getting Dybala. I think this starting 11 would be magnificent. Verratti and Kovačić are worksehorses who aren't egoistic,they'd help the defence so much and it would free-up Modrić who's in the same position as Marcelo now,being overloaded with duties. Not to mention that players like James,Benzema and Isco would have so much more freedom.
Better defending, more connected DEF,MD and ATT, players having more freedom and not being choked by the laziness and egos of Bale and Ronaldo. Much better dribbling and passing since Bale and Ronaldo don't excel at either.
