What did you people think a rebuild was going to be? One window, all problems solved and we go back to CL finals and 10 Scudettos in a row?
Reality is aside from Pogba and the RW that will come soon for everything else you have to wait for sales and you also have to wait for other clubs primary targets to fall through to come to us and ask for our garbage.
You want a left-back? Pellegrini and Sandro are there
You want another midfielder? Arthur, Ramsey, Rabiot are there
You want a striker? Kean is there
You want a CB? Rugani and Demiral are there.
And no, it is not as easy as saying "fuck them, just put them in the stands or gift them for nothing".
I know it's sexy to shit on everything and demand everything all at once, but Arrivabene and Cherubini literally have not put a step wrong since they were put in charge. You don't have to make up your minds about everything now, 2 months before the season starts and almost 3 before the window closes.
They reduced the wage bill for over a 100m already, made tough (and correct) decisions on contract renewals so far (yes, even MDS will play almost for free and be 3rd choice on both sides) and all the players they signed were very good signings. Except maybe Kean but even he is still young and at least you won't make a financial loss for any amount he is sold.
