have you watched him in Brighton? I think De Zerbi has evolved a lot since his Sassuolo days. He seems much more mature, and he is bringing in the results in PL with an average roster.
Maybe it just because Allegri has made me completely depressed and I need to convince myself of something, but I really think he could do a successful rebuild with our current roster, and play some entertaining football at the same time. It might take some time, but I think he could get the best out of our young players.
I think with 4 new players we could have a team De Zerbi could work with. I assume Cuads, Rabiot and Di Maria will leave, and we can keep Dusan and Chiesa. I think Pogba will leave since we most likely wont play in Europe next year. Woj is not good enough with his feet, so we would need to get rid of him some way.
Bonus is he already worked with Loca and made him look good.
