Inter Milan are on a different form entirely, just watching how they humbled Atalanta who just trashed Juventus days before their game with inter. Though the title race is still open for the three sides who have relentless being on it this season except that Napoli has to drop points with Atalanta too in their next two games that's when we might actually give the trophy to the defending champions Inter Milan but they have to continue winning their remaining games to maintain their 3 points lead on the top.
Indeed, Inter Milan managed to move away from Napoli or lead by 3 points but don't forget Inter Milan have some important matches ahead such as the Champions League and the Copa so this will have an impact on their performance in Serie A well, this is an opportunity for Napoli to catch up or take over the top of the standings. The Serie A title race is still open for both teams and we can't confirm yet which team is truly safe, while Atalanta could be excluded from the race imo because their efforts do not come close to those of their competitors.
The difference of 3 points is also fairly heavy in my opinion, Napoli are not easy to get it unless intermilan can be defeated it can be a different henario in the Serie A league, seeing how Interilan won the match yesterday and Napoli were held in the Imban by Venezia to make the position further, next week the match against Udinese which in my opinion in my opinion Udinese was quite strong and tough in giving resistance, it would make Inter Milan difficult, and the match in the league made it enough to make the Milan. It could have affected the energy possessed by their players and could have made injuries that will fight their performance, this can really be an opportunity for Napoli.
