I think the reason is because Juventus is safe enough to be able to get a ticket to the Champions League next season so they don't have any greater motivation for the rest of their matches this season.
It was really surprising when Juventus couldn't win against the Salernitana team who were certain to be relegated this season and even Juventus almost lost, but fortunately there was a goal from Rabiot in the final minutes of the match to prevent Juventus from losing at home.
And there was a lot of player rotation carried out by the Juventus coach because they were looking at the Coppa Italy final against Atalanta, I think this was an influence on Juventus' decline in performance.
Yes, maybe that is one of the reasons why they keep getting draws like this, but in my opinion that shouldn't happen, because the opponents they face are not a very strong team, so even though they have guaranteed themselves to qualify for the Champions League next season, They must also be able to maximize the games they play to win.
When they get used to things like that, it is feared that it will become a habit that will be difficult for them to break. They are a big team in Serie A, so they should be able to show better. Not only that, what was very disappointing was that the team that managed to hold their draw was a weak team that was certain to be relegated. Maybe I would think it is normal if the opponent they face is a team that is also strong and at the same level as them. However, they got these results with a team that was far below them.
