Yes, hopefully, Como's efforts in spending a lot of money on players in this transfer window won't be in vain. However, I believe Como isn't just looking to stay in Serie A, but also to secure a spot in the Europa League. If they were solely focused on stay in Serie-A, they wouldn't have spent more than €100 million on all the new players they've acquired this season. This massive buying would be impossible without a Europa League as target goal.
I think this condition is automatic. If they have many quality players, then they will do well in the league. Then the following season they will be able to go to Europe. So I think they do have a big target but I think realistically for now is to win the league or end up in the top 4 or in the top 6 to participate in the European Conference League qualifying participants. Indeed Como have become a very serious team since they were able to get promoted to the A series.
If you look at the club's transfer policy, the players who come are young. So I think Tim is making transfers for long-term achievements. They didn't bring in star players, but young players who have the potential to become good players.
