Juventus really need to overhaul some of their players and also the tactics they will use for next season and Igor Tudor must also realize that the Juventus team is in poor condition so he must be able to make better changes for next season so that Juventus' decline is no longer visible in the next season. Because teams like Napoli, Atalanta, and Inter Milan could be better than last season so Juventus is expected not to be so far behind when the team was in the next season. Although I am also still not sure that Juventus will be able to be in the top four of the standings as happened last season.
They are already getting some players, and they already have some players on sale. So it is obvious that we are going to see them have some changes, we just need to see if those changes will actually impact them good or bad. I get that it may not look like it's a good one yet, but it is clear that we are seeing them not do a great job so far. If they make better changes, and those changes work, and those new players actually helps them out, then they could do better.
I still say that top four is a good finish for them, consistency is important and finishing top four would allow them to be getting better with time. You do not become great overnight, not in a single season neither, so it may take a while for them to be champions yet again, so they need to use that time.
