TBF, he rolled with it a year ago, when Seedorf was still coach (till like July 2014!), and was still thinking he would stay, Pippo was already in Arcore summits, and vacationing in Ibiza begging Menez to come and was begged to be coach by B+G since like April
Pippo's getting a taste of some humble pie. He also acted extremely poor with Allegri.
April? my impression is since the week after Seedorf was appointed.
Galliani never wanted Seedorf opinionated ass there, too much character... he had just lost half of his powers to Barbara who took a stand against the stupid decisions he was making... last thing he wanted was another guy who was not a "beni oui oui".
the month Seedorf was chosen by Silvio, Pippo (then primavera coach) had offer from Sassuolo (irrc) and was interested. had a meeting with Galliani before making his decision.
besides the promise of "stay put, the bench is yours in the summer, no doubt!", i don't know what else could have convinced him to not accept Sassuolo. Sassuolo, which could have been a very good starting point for him, considering how he did here. had he failed there, and gotten relegated it would not have been such a big deal, newly promoted, it's pretty much expected.
i don't see Miha meshing with Galliani either, when he'll start benching Galliani's godsons for lack of productivity, lack of sharpness, lazyness or for simply not being good enough.
