In the Champions League, Inter Milan has strong teams like Barcelona and Bayern Munich in their group. So now Inter Milan should aim to do well in Serie A. Their performance in Serie A is still not good. They lost two matches. Inter Milan's goal is to win the title. If they perform erratically like this, they will not be able to win the title. Teams like Juventus and Inter Milan are not able to play well. Looks like we'll see some new champions this season. I wouldn't be surprised if Napoli or Roma win the title.
I agree, they are not good enough to go beyond group stages, they had a very unlucky draw and they will end up with a loss more often than a win, both Bayern and Barcelona will beat team twice probably, unless something exceptional happens. This means that they had a chance to win last year, and they won it a year before, I do not think that it would be that much of a stretch to wait for them to win it this year as well.
Juventus built a great roster but they are mainly injured or missing, which means that they are out of the picture for the time being, Milan is good and all but they have too many players who wants to go to better teams, so Inter could use this to win the title.
