Di Maria is a freebie and necessary, with Chiesa out for half a year. Scratch Di Maria and put another name, it will be a bigger investment, and then you have 2, 3 or 4 starting caliber wingers when Chiesa is back, with the midfield still lacking.
I fear we plan to keep some of the bums in the midfield. Zakaria and Locatelli will stay, good chances McKennie will too. Then you have Rabiot who we all love, and Arthur. Allegri might be fine with Rabiot and demand just one big name there, while Arthur is loaned. Then fill the 6th spot with Fagioli or Rovella. That could leave us enough money for a LB and a starter LW, but it would mean we get to see another year of Rabiot
