I'd sell Dybala, Benta(only if we get 100%), Rabiot, Berna(although I think his value has tanked too much) and Ramsey to some EPL team with money. I'd honestly even sell Demiral if somebody offers a crazy high offer based on his age and potential.
To tell you the truth, the only players I would not sell are De Ligt, Chiesa and Arthur.
This team is in some serious need of game changing midfielders and at least another winger/wingback.
