Don't be pessimistic like that before the season starts because all teams will compete according to their abilities and will give a fight to any team. I think Lazio, Milan, and Roma will make the Italian League even more interesting next season, plus the strength of Inter Milan and Juventus who might make better improvements next season. So you don't have to be pessimistic for now because all teams have the same chance to become champions if they have high consistency in achieving victory.
Yes this is also true, all the teams have leveled out, but leveled down.
I don't know if i should consider this thing that happened a victory or a defeat. i would choose the second option honestly.
In fact i am sure that in the European cups we will be rubbish
