Faaak No! Selling your best and most marketable player for the 3rd summer in a row is a shitty business model. We might be able to dominate the watered down Serie A (not sure for how much longer tho), but in the long term it is a damaging strategy which takes us further away from our goal of European glory.
Now, if Dybala leaves, and in exchange we are guaranteed James, Verratti, and Morata, then I'm all for it
