You are right. At the moment Juventus needs the cooperation of Maccabi Haifa. If Maccabi Haifa can beat Benfica in their next home match, Juventus will have a chance to qualify for the next round. But despite Benfica's defeat, the Juventus team still needs to win against a strong PSG team. And I'd say it's more difficult for Juventus to get full points against PSG. PSG is a strong team, and they are in very good form right now. Neymar and Messi have been able to continue to perform well consistently. And if the trio of Messi, Neymar and Mbappe can play well, Juventus will never be able to win against PSG.
Juventus does not need any cooperation, they need
a miracle to qualify for the knock out stage. The chance for them is so low, even if they can win against PSG and Benfica, their chance is still relied on the other matches. I would say for Juventus fans, do not hope for the miracle too much to see Juventus qualify for the knock out stage. Hoping them to win the last 2 matches is fine, at least it wont look really bad if they fail to qualify.
