I'm sure we'll be in top 4.
We'll be in top 3
Let me remind you all that Milan had 2 or 3 more similar wins this season (Lazio 1:5, Sampdoria 0:5). When they play against attacking teams (something that Napoli certainly is) they are always superior.
Yeah, they have more options in attack and they won't suck like they did so far, but they'll lose a lot of points till the end when cattenacio will be played against them.
We won 10 points in last 4 matches. One draw isn't a reason to be scared. Roma, Fiorentina and Milan all play in Europe, they won't win all their matches.
I'm 100% sure we'll get the CL spot, which was our goal at the start and during this season, and it's the spot we already hold.
But i agree that for the next season we'll have lots of problems without changes in the team. Playing CL and serie A isn't the same as playing serie A only. Just take a look at Lazio.
