It seems that Como is building something much bigger because as a promoted team they are much better than other promoted teams, the recruitments they have done previously have mostly yielded satisfactory results, and now they have Delle Ali who can be relied on to strengthen the midfield.
Cesc Fabregas is starting to show his magic hand as a manager, I think beating Undinese with a landslide score yesterday has changed the views of some people to always not underestimate Como. Currently they are in the top 13, a fairly far achievement, but this month is their proof with their ambition because in a row against strong teams, if they can get through this challenge this will be a momentum for them.
Como can no longer be underestimated after we saw how they won the match against Udinese with a really convincing score. But a tough test will come for this team in the next match, namely against Atalanta. We know that this season Atalanta has really turned into a very strong team. Even in today's UCL we have seen Atalanta succeed in beating their opponent with a big score of 5-0. So in the match against Como, it is likely that many people will favor Atalanta. Moreover, Atalanta will try to avenge their defeat by Como in the previous meeting. But it would be very surprising if Atalanta were held to a draw by Como or even lost.
The second half of the season is the toughest test for Como because their match schedule every week meets strong teams, Atalanta is the first test for them, on paper of course many agree that Atalanta is favored, but as you said in the first leg Como managed to beat them as the away team, the result is capital for Cesc Fabregas troops in the second meeting next week, then is Como able to beat Atalanta for the second time or Atalanta does not want to repeat the same mistake? What is clear is that currently both teams are in their best form so any final result can happen.
