you don't seem to get this one either. it's not about allegri leaving (tho i like the guy and i think he's a top coach), but about the potential alternatives. simple haters would welcome simple solutions, but firing allegri wouldn't solve anything, but create an other, even bigger problem. coaches like inzaghi, mihajlovic, sarri, edf (and the list goes on forever) are rumored to be taking over and there's no benefit in bringing in one of those coaches.
if agnelli manages to lure pochettino away from spurs, i'm fine with a new direction. i'd be okay with zidane or klopp. but these coaches are unavailable, so replacing allegri with some dummy for the sake of it would be like an end summer panic buy. think hernanes. it might work, hernanes wasn't the flop we expected him to be, but we can do better.
