Out of all these, I always fear Juve the most. No matter what, form or problems in coaching and whatever, they still do have quality squad on paper and also a proven coach. Whether they fail to perform at their expectations is another thing.
Both Inter and Juve have better teams than Milan thouigh. Napoli and Atalanta are both doing very well but there is no way that one of them wins Scudetto. It's basically an Arsenal run, like remain at the top for some time and eventually hit the downhill.
Not sure which year it was, during Sarri's time in Napoli while Juve was doing pretty bad and of course Inter and Milan were basically out of race, so it was between Juve and Napoli, and the latter ones were like 10pts ahead and still managed to bottle it. Could be year 2014 or something? I said after that, Napoli will never win Scudetto
We just need to take every match seriously and know the importance of points, and then we will be fine.
