You can't put that blame on Max tbh.

Gee han....I think till one of us dies, we shall play this drama all over again. You attacking the coach, and me saying, "Hey, he's not all bad!".
Anyway back on point, I think that this is probably the first time in 11 years that Milan has played with 3 at the back. There was bound to be miscommunication, and of course the players not being used to it, meant they were out of position and rushing to cover- meaning not only last ditch tackles but also getting fatigued.
For me, a 3-4-3 with wingers instead of wingbacks is a bit silly and unbalanced. If we are going to play 3 then I would:
-----Yepes----Mexes----Zapata-----
Abate------------------------------Urby
------Monty----dJ------Noce/Prince---
-------Bojan/Pato-----------SES/Robinho-------
-----------Pazzini/Pato-----------------
Who would have thought start of the season that SES would be the first name on the team sheet.

The above formation is the most balanced I can think of. It is a little weak down our right flank, because if Monty is busy doing creation, we are a bit open to a counter. But Abate is our strongest wingback since Cafu... so

Finally, if Allegri is staying:
- Europe is not optional.
- He needs to decide really quickly what his chosen formation is.
- Because we have to buy in December based on that. Oh yeah Unc. Fester. That's not optional too.
- If we're sticking with the 4-3-1-2, then I guess we're stuck because we need to buy in at least 3 top players, and outlay of at least 35 million.
- If we're going to stick with the above, I would probably get someone in that mid-field who is truly magical even if we need to splash out 20. After that hope to get into Europe with all our might.
