Juventus know that if they win Europa League, they will be awarded a special ticket to join Champions League in a next season. They do know that it's impossible for them to complete Serie A in top four because they have too big gaps with top five at the moment. The deduction with 15 points is harmful for Juventus chance to finish in top four.
Winning Europa League is not easy but it is a more realistic task for them than ending in Serie A top four. They don't have to chase any club in Europa League and task is beating each opponent to the last one in final match. Juventus have enough good players and a very experienced coach in cup format, Allegri that can help them lift Europa League.
That is going to be a big deal for them, and knowing that they are doing a very tough job right now, it's going to get even worse. They are not playing well enough to win europa, they are not playing well enough to beat anyone to be fair, they are losing to everyone and failing miserably right now.
This is why I would suggest that the best thing to do at this moment is to make sure that they are ready for next season. Forget about this year, just focus on next year and maybe they will get a better manager and a better team. It's obvious that they were trying to rebuild the whole team but as we can see they failed, so they need a better management.
