Inter Milan is in its best performance after several clubs such as Napoli seemed difficult to defend last season's title. It seems that this season is Inter Milan's opportunity to win in every match in order to win the Scudetto easily, but Inter Milan is aware that they are still in the shadow of Juventus who most likely to tackle him in the future, Juventus' performance is highly questionable, Juventus has the potential to be a candidate to win the scudetto this season, even though their concentration is often lost in several important matches, this could be a big threat to Inter Milan this season.
Inter does look like they are doing quite awesome there is no doubt about that. I am not saying that they will win the title because there are still some time to go and Juventus ain't joking around neither, just a 4 point difference could be closed at any moment so Inter has to be careful. However, if you ask me who looks like more likely than any other team then I would have to say Inter, not only they are at the top with four point difference, but they do look better and keep getting better as well.
This is why I believe that it is going to be quite the big trouble when it comes down to all of this, it has to be Inter that wins it. Plus, they had a UCL run last year, so they weren't bad and made some money, and they will make a ton of money again if they win the league this season, that's a great consistency a team really needs. If you keep getting money like that all the time, then you can build a decent team, and when you do that, you keep winning.
Inter position at the top of the standings is not entirely comfortable because it is only 4 points behind Juventus in second place. In the second meeting there was no winner, this can be a reference that before the difference in points gets bigger, concerns continue to surround Inter. As we know, Juventus only focuses on domestic competitions, this is luck in the strict sense, Allegri has more time to analyze and prepare his team so they can perform optimally.
For Inter, they are ready to face any challenge, their target is quite clear if you look at the depth of the squad they have built this season. So far they have only lost 3 points, their goal productivity rate and conceded rate are quite good. A balanced squad depth between the lines is the key to Inzaghi success in bringing his fleet to a consistent performance, even in the UCL group phase, Inter also performed impressively by going undefeated.
Inter success in reaching the final last season allowed them to talk a lot in the transfer market, because they got big bunos. So being able to attract several players including Pavard, as well as releasing Onana to United gave them big profits. I agree with you, achieving success means making big profits and being able to build the squad sustainably, that's how the football industry works.
