They are doing well compared to last season and they still have every chance of competing and winning the title despite dropping points, other teams will drop points as well as the league progresses so there is no need to panic at all.
That's the problem, Inter has a difficult game in the next round, it will be a game against Lazio who defeated Napoli twice in less than 7 days. If Inter wins they will be at the top of the table and Inter's next games are games against easy teams, so I assume that Inter will be able to win the next 6 games. Only after the next 6 games will Inter play against strong opponents like Juventus, Milan, Fiorentina and Napoli. That's why in my opinion if Inter can win the next 6 games and then win the games against Juventus, Milan, Fiorentina and Napoli, then Inter will be champion.
