UEFA's punishment made a bad season for Juventus and the players or their coach are not guilty at all. They were having a good performance but even if you get the ticket for the next Europa League but they take the ticket from you, what is the point of all the good performance they had? I think in the next season Juventus will race with the top teams for the Serie A title like they deserved.
In fact, nothing was in vain with the good performance that Juventus had last season, because Juventus can still use it next season to prove that they are strong and also deserve to be champions. And the only step that must be taken by Juventus if they want to go to UCL is to win Serie A next season or at least be able to finish in the top four in Serie A because that is the path they really have to take. Because Juventus next season will only be in the European Conference League after they finished seventh last season in Serie A.
It was indeed quite in vain because otherwise they would be playing the Champions League and that would turn things into the positive direction for them a lot. Imagine what a difference it is for a worldwide renowned club to play the Champions League or not. The consequences are quite heavy on many ends. Less people are going to watch their games, less players are interesting in signing a contract with them or even stay with them at all. The income for the upcoming season will decrease significantly due to lower marketing success. There are even more negative consequences, I would say that the last season hit them hard with that punishment.
