I don't see why not tbh, in my opinion all the players we buy besides fowards will be covered by sales. We have Melo, Krasic, Ziegler, Elia, Pazienza (about ~25-30m imo) + another 5 at least from other players. Let's say that's 30. So far we've spent about 19.5 on Asamoah, Isla, Leali and Pogba. Now if we add 25 to that for RVP and 20 for Jojo that's only 64.5. If you remove the minimum 30 from players sold we've only spent about 35 and last season we had a total outlay like double that. Add a couple more players (maybe CB & LB) and total outlay = around 50. Don't forget Agnelli said we're expected to make heavy losses again this season but after that everything will be better once we have CL income.
Right, but remember the salaries that are coming in, too. We're going to be adding some cash there, plus it sounds like at least 5M for Verratti, also linked with some other players in potential swap deals, like El Kaddouri. Who knows what will come, but we still need to be aware that Juve has taken a couple of heavy losses the past couple of years, and has installments to pay on previous purchases.
I just wouldn't get hopes up too much, considering we've really already spent 35M on 3 players, plus a couple of decent salaries probably (Should really count the full value of Asamoah and Isla, as vast majority of players are bought in installments).
Other than that, problems become mostly logistical (do clubs want our players - Fio/Gio specifically - that type of thing).
Anyway, 3:40AM here, time for sleep.
