I think it would be better to consider Inter as contenders for the title too. It's not easy for them to change strategies and tactics after four years with the same coach, so I understand that this slow start is more than normal.
The more teams there are competing for the trophy, the more exciting the championship will be! I can't remember a Serie A season where four or five teams were in contention for the title until the end of the tournament.
Milan, Napoli, Juventus, Roma and Inter all competing for the title? We haven't seen that since the 1990s, perhaps.
In my opinion it depends on how they play the next matches, given that from the point of view of points they are not in the same position as Inter last season.
and it also depends on what they do in the direct clashes with Milan, Napoli and Roma
everything is quite strange but interesting
If I'm not mistaken, Inter are only two points behind last year's tally, so technically they are in line with last season's results. The most surprising thing is that the top of the table is more crowded than last year.
Inter have already lost their first head-to-head match against Juventus, and you're right, everything depends on how they react and approach the upcoming head-to-head matches.
