@Porque to my knowledge Chadi will be officially sold to Betis anyway, there isn't much to do the summer for him but to get the money.
Pablo Torre, Dest, Eric Garcia all should get us some income too, possibly J. Araujo as I have the feeling he will face Emerson fate, Lenglet & Fati are other expected "loans" that should get us some margin if we are in the 1:4 rules (whatever the ratio is now).
If we are just short of the 1 to 1 rule, I would think those will be enough to get us Cancelo, Roque & Fermin registration and maybe a cheap signing.
PS: I do like Mbacke a lot, not sure if he has a future here or even as a resale guy, given his age.
