Italian teams perform surprisingly well in the Champions league platform . Even though they are not considered favorites for the final, they perform quite consistently in the knockout rounds. Anyway, I do not think that will happen this season. Inter Milan's position is shaky. Napoli's overall performance is somewhat stable, but their attack is weak. Even though they can do well in Serie A, I do not expect a very good performance from the team on the Champions League platform. On the other hand , Atalanta's situation doesn't seem to be very strong so far. If they don't improve their performance in the upcoming matches, there is a big chance that they will be eliminated in the first round of the Champions League.
I think that none of the Italian teams have the ability to compete well in the Champions League. We can raise some hopes for Inter Milan and Napoli, but their recent form and team strength are not strong enough for the Champions League. Inter Milan's form is not very good right now, while Napoli is playing well but there are doubts about how suitable they are for the Champions League. It would be foolish to expect the rest of the teams. However, this season I will probably see the Spanish and English leagues dominating and one of these two leagues will play in the final.
This year could be Real Madrid and Barcelona's year. Last year, Barcelona were eliminated in the semifinals. This year, they have a chance to reach the final. Of course, the match schedules are also crucial. An early elimination could change all plans. If Real Madrid faces a strong opponent in the championship finals before the finals, they could face an earlier elimination. Italian teams may not pose much of a threat in the Champions League this year, but Spanish and English teams will be very dangerous indeed.
