I also don't think that Napoli will be able to win Bologna due to their poor performance with Verona, it makes me doubt their strength. However, it is possible that Napoli might be able to defeat Bologna because they might have learnt from their Mistakes. Bologna is also a team that cannot be predicted in their next match.
The rest predictions are possible to come out as predicted but it is still a 50-50 chance of coming out that way.
As a result of Napoli's defeat in their first week in Serie A, many people now have doubts about them in the coming week. But we can't actually give Bologna a favorite because they couldn't beat Udinese in the first week. even though Bologna was the host in this match. And even Bologna only scored a goal from a penalty kick. Meanwhile, Udinese equalized the score with a regular goal. So I think Bologna is also difficult to predict as you said. So the Napoli vs Bologna match will indeed be the most difficult match to predict. because both of them were not very convincing in the first match of the season. Maybe I'd rather skip this one.
