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.
It is very difficult for Inter to qualify for the knockout phase. but sometimes clubs show different results between the domestic league and Champions League. Inter and Barcelona have the same points so far on group standing, so Inter still has 50% chance of qualifying if they are playing well in UCL. Serie A still has a long way to go, but it's still possible for Inter to win the title. If AS Roma wins, it's a surprise for me, because mourinho can bring the team to a title they haven't felt in a long time.
The domestic league and the Champions League have different atmospheres, because the competition in the Champions League is fiercer than the Domestic League. Inter and Barcelona are both victims of Bayern Munich ferocity, these two teams will fight each other to get the three points. Inter are still struggling to qualify for the knockout phase because Barcelona is still there, but Inter chances are still wide open if they are able to get additional points in the next match.
Roma chances of winning the Scudetto this season are very small, even though they already have a squad capable of competing with Inter, Milan and Juventus. But Roma inconsistent performances have made it difficult for Mourinho to bring Roma to lift the title that the Olimpico public has long coveted.
