This is my humble opinion:
GK- we are fine but probably getting De Ge anyways. Not a bad thing.
DEFENCE- A new LB,like Ricardo Rodriguez. RB is covered and so is CB if nobody leaves.
MIDDLEFIELD-I'd personally sell Kroos for huge money.We're alrwady stacked in MF and I'd give Isco and James more playing time.
ATTACK-Keeping Bale is inevitable but he's good im his new role so far.Sell Benzema if not cleared.But Aubameyang or Lewa as direct replacement. If Ronaldo,wanta to leave on his own,get Dybala.
Example:
Modric-Isco
James-Bale-Dybala
Lewa/auba
Example 2:
Casemiro-Modric
James-Bale-Isco
Dybala/ST(lew,auba,benz,cr)
Thw first one is CR-free. The whole team is tracking back and helping. Modric and Isco are bossing the field and helping thw defence and counterattacks. Its tiring and thats why Kovacic is always subbed in 60-70 mins into the play. James and Bale have deadly long shots and they break down buses. With Isco,modric and james we dominate possession. Also pace overload with Auba,Dybala and Bale,resulting in the best counterattacking team in the world.,the team fits.Perez's style since there is barely any defence.
So my wish is to give Isco and James safe starting roles,but and start Dybala. Trust our current backbone,not overhaul the team.
I'm typing on the phone o there'll be countless mistakes as you can see.
