We just weren’t very good this year. Nowhere close.
The first 3 years of Allegri’s tenure I would have said we could beat anyone on our day when fit and in form (assuming we are the team that gets that little bit of luck).
The past two years, while we have a good team, we’re always in brutal shape physically, can’t be arsed to show motivation frequently, and can’t seem to lock down a coherent set of tactics consistently. Top performances show up, but they are rare.
