Madrid don't do things half ass. They'll sell Bale, Benzema, Theo, Marcelo and Modric to recoup money or at least cut wages and spend 400M on something like Eriksen, Hazard, Telles, a 9 and De Ligt. I don't think Hazard, Telles or De Ligt will even be that hard for them, though identifying a 9 (it's a bit barren out there) and getting Eriksen will be tougher so maybe that new CM is Havertz or Ndombele or Verratti or someone else.
Hazard/Vinicius---------9/Diaz--------Asensio/Vazquez
--------------------------------Eriksen/Isco-----------------
---------------Kroos/Kovacic---------------------------------
------------------------Casemiro/Llorente-------------------
Telles/Regulon------------------------------Carvajal/Hakimi
-------------Varane/Nacho----DeLigt/Ramos---------------
----------------------Courtois/Navas-------------------------
That's a hell of a team again with Hazard, Kroos, Casemiro and Carvajal as the still performing at a high level veterans in their late 20s surrounded by guys in their mid 20s prime (Courtois, Eriksen, Varane, Telles) and prodigies ready to blossom into world class players (Asensio, De Ligt) and whatever 9 they get to replace Benzema who can score more than 11 goals in 26 league starts.
