The club have appointed De Zerbi to a long term contract, knowing that the squad decimated by injuries and likely heading for the Championship will need to be rebuilt (certainly if we go down).
How anyone can expect to see an immediate improvement after just two weeks in charge is beyond me.
De Zerbi has no doubt discussed the fragility of the squad, drawn up a plan should we go down, and would have agreed a transfer policy moving forward.
It's fucking obvious that with a decimated squad, whichever manager came in would be working in very difficult circumstances, and if anything is "bizarre" about the situation it's that you think there's a magical formula to fixing a twenty five year issue in just three months.
I don't think its anything more than wishful thinking and hope that a new manager can get us of this quagmire we found ourselves in.
