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.
Honestly, today's Serie A is a very interesting season to watch the competition in Serie A, their game is unpredictable, even the current seeded club can't play better than the club that is now in the top 4 standings. I agree I wouldn't be surprised to see Atalanta, Napoli or even Udinese coming out as champions this season. But there is a little concern for me that they can't maintain their good form today. Because we still see it very often in Serie A. For example, last season was a very unfortunate season for Napoli because they couldn't keep their hopes up to stay competitive and had to lose consistency at the end of the season.
Yes last season ended very badly for Napoli but this year they seemed that they learned valuable lessons from that. There are Fiorentina and Lecce draws in the 3rd and 4th weeks, these are the middle row teams. 3 weeks ago they beat the last champion milan in san siro, good job. In order to have a clearer opinion, it is necessary to see the games of 23 October Rome and 5 November Atalanta. In fact, on November 12, there is a home game with the 3rd placed udinese. In the meantime, there will be a sassuolo match inside, they will win it comfortably. Then January is pretty decisive. On 4, 15 and 29 January, respectively, there will be inter juventus and rome matches. Both the experience of the team is better and there is no elite team that can force it from behind, as in other years.
