Actually agree with this. We still have, by far, the best team in Serie A and will rightly start the season as favourites due to that. We do need a few new additions and for some old players to be shown the door.
We need replacements like never after 2011.
In 2015 we lost three great players (Pirlo, Vidal, Tevez) which was an incredible loss, indeed. However we still had that top defense intact (Buffon, Chiellini, Bonucci, Barzagli, Evra/Sandro, Lichtstiener) and we replaced Tevez with Dybala and Mandzukic. We kept Pogba too.
This year we already lost our most important midfielder and replaced him with Arthur. The defense is incredibly shaky. The midfield is the worst we ever had. We don't have a pure striker. We won this season on muscles with Ronaldo and Dybala. Next year we will need much more. In 2015/16 our defense won the scudetto after that terrible start, by conceding some 7-8 goals in almost 30 matches. Right now we don't have such strong part of our team that will push us to the scudetto against better opponents than those we had in 2016.
Of course, some luck in mercato and new purchases like Kulisevski, Arthur and some others might do the trick, but like I said, we need replacements like never before and we will need great luck with the new buys. Perhaps luck like the one when we hit the jack-pot with guys like Vidal, Pogba, Lichtstiener and made a master purchase in Pirlo.
