This Italian League season, Udinese has been the most outstanding team I have ever seen. I have a hunch that this Serie A season may bring perhaps the biggest shock. They will likely surpass Atalanta and Napoli in the league standings sooner rather than later if they keep up this pace of scoring a decent amount of goals and producing quality passes to control the game as they see fit.
Udinese has been playing just similar to Atalanta seasons ago when they suddenly rose in Serie A. More impressive, Atalanta manage to continue it about 4 seasons later. So far in this season, Udinese are good but they are far away from what Atalanta have achieved recent years.
I don't think there will be big shocks in Serie A this season because Udinese are lack of many things to have stable performance in a long season. What surprise we can see is top four, not Scudetto. This season, two Milan clubs will be challenged by more clubs from Napoli, Atalanta to AS Roma and Lazio. I don't consider it is a shock if any team among Napoli, Atalanta or AS Roma win Scudetto in this season.
