I think that the next season is of existential relevance to them. They won't disappear or anything when they have another bad season, but they will have lots of difficulties to rebuild their team should they miss the Champions League again.
That's how they should be. This previous season became a very valuable lesson for the club and also for the players and all parties in general. Here, we can later see how serious Juventus are in improving their team, in improving and developing this team very well this season. Not only that, Juventus also have some quite complicated homework on several fronts and they are trying to fix it. If they failed again, this would be too much. At least they can enter the UCL next season, if indeed they can really improve their performance, without any more sanctions.
......But apart from Osimhen, I personally don't care if Osimhen stays or leaves because either way, it's clear that defending the title is a tough matter. What's more, Napoli is not a team that is always at the top of the standings every season so it will be natural if later Napoli cannot defend its Scudetto title.....
If only Oshimen would have Napoli still have more trouble defending the title this season, especially if Oshimen moved later. This will make Napoli itself worse. moreover, there have been several changes in Napoli, not to mention they have the newest coach, not Spaletti anymore. Surely they are trying something new again even though Napoli say that Rudi Garcia may have almost the same way and tactics. But we don't know what the results will be yet. So, it's still a guesswork. That's why many people doubt if Napoli can defend the Scudetto title or not.
