Think Allegri is gonna leave. Constant smoke from the media and cryptic comments point towards the obvious, not to mention the fact that you really can't trust Beppe's reassurences after a couple of cases of him almost blatantly lying while fixing things behind our backs: Beppe denied being after Higuain when the deal was close to being done and he also denied Pogba leaving when Raiola said it had been negotiated with the management for a longer time. Wouldn't be suprised if they've already reached a mutual agreement and are just playing down hype to keep the results rolling til the end of the season.
It wouldn't be a catastrophe though; if Allegri is truly losing the dressing room like reports say then it's good to fix it before it starts affecting our performances. Allegri is a world class coach, but he has clear faults too and if he fails to make it far in the CL I believe we have reached the limit with him. Lots of good coaches to choose from right now too: Sousa is under fire and could leave, EDF will probably like a jump up in quality, Guardiola is under fire (I know most of you hate him), Klopp is under fire too after bad results, Emery is a possibility if PSG fail to meet targets and it wouldn't be far fetched to try and lure the likes of Sampaoli or Jardim here.
