First, the initiative to qualify is not in your own hands.
In the Champions League Group F, before the final round, Inter Milan played against Slavia Prague in the Czech Republic at home, and the result was 1- 1 draw. Then away 1-2 lost to Barcelona. I didn't return to China until/kloc-0 defeated Dortmund 2-0 on October 24th. Inter Milan's score is very unfriendly. In the last game, Inter Milan need to win Barcelona. Dortmund can only advance if it loses, so it has no initiative to qualify.
Second, the Nerazzurri distracted league.
Everyone knows that Inter Milan has been away from the Serie A championship and even the top spot for many years. Now 19-20 season, although it occupies the top spot with a slight advantage, it is also a smooth start, and Bamba Juventus has been under pressure. So the Nerazzurri's fighting spirit will be divided by the league title competition. Even personally, the Nerazzurri's primary goal is not the Champions League, but the League title.
Third, the schedule is unfavorable.
Inter Milan fought hard in Rome before playing Barcelona, and then they will challenge Florence, Naples and other strong teams away. Such a high-intensity competition is the time to really test Inter Milan, and such an unfavorable schedule is also unfriendly to Inter Milan's qualifying! Moreover, Barcelona is a frequent visitor to the Champions League in recent years. Barcelona, which has won the qualification of the annual stability group, will definitely cause a lot of trouble to Inter Milan, and may even score all three points at the Mei Acha/San Siro Stadium. Generally speaking, Inter Milan belong to the death group in the Champions League, so it's normal that they can't qualify. In addition, there are strong signs that Inter Milan is recovering. I hope Inter Milan will return to the top as soon as possible.
