Har question. Their biggest asset is their midfield, and i think it's just as good as last season, might be even better. Very balanced, and with experience (Gonalons) and potential (Pellegrini) on the bench. However, a lot of changes at the back, and it is way to early to make conclusions, but i expect it to more shaky in the beginning of the season since the players they brought in, in general, does not offer a lot of top european experience.
My bet right now would be them to gather fewer points than last season, both because they lost a main offensive outlet and changed so much at the back. Also they changed the coach, and we can only guess how that will turn out in the short term, even if most people rate Francesco.
