As a long time Inzaghi supporter, my biggest pet peeve with him is not motivation, not defending is not an consideration nor his subs, nor all the normal listed accusations on FIF.
It is rather he doesn't care about or observe enough the players' status or their true limitation of style; to me he does not seem to evaluate a players' attributions or fitness for his tactics; he merely plugs them in. This might cause by the belief of stabilizing the locker room (e.g. Handa) or personal preferences or blind impression, I am not sure of the cause, but the behavior explains the lack of rotation, players trouble executing the strategies or tactics.
(The subbing booked player off is also a good example of so, it is like no extra evaluation on the player of the odds of another yellow card, or any other adjustments)
He has very good tactics, but he doesn't tinker around it when the other factors are not align with it, like no players are able to carry the role etc.; however, I am not sure if this is entirely on him, cause that also indicates the club is not supporting him with the right resources/players. e.g. None of our strikers can do counter football at this point, unless they pick back up their fitness or so.
Sacchi's comment on him after the Porto game was very spot on, also did acknowledge him as a potential great coach, but improvements are needed; I really want him to success and grow with us, and also find a way to integrate the young players into the roster.
The only replacements I would accept would be Mancini and Ancelotti with our current budget, which is impossible at this moment.
Don't fucking bring Cunte back.
