We could see a three-way championship race between Inter, Napoli, and Juventus. Inter and Napoli were in this race last year and will be competing in the UCL this year. I'm confident they'll continue this run in the league. I wish them an enjoyable season.
If you didn't know, Juventus will also be in the Champions League as they finished 4th last season. In this sense, all teams will be on equal terms as there won't be a situation like last year when Inter played both and Napoli had an advantage because they weren't in European competitions at all. But as for the chances, I don't understand why you rate Juventus so high, the main favorites are Napoli and Inter, Juventus is closer to Milan than to this pair.
