Yes, that's right, the worst case scenario is Benfica letting Maccabi Haifa get points which will certainly make Juventus exit the European tournament completely. But I personally don't believe that will happen because after all, PSG and Benfica will also of course still target to win the group and with that, PSG and Benfica in my prediction will still be certain to win on their last matchday.
For sure, it will be difficult for Juventus and Maccabi to win tonight's match. although, both have the advantage of playing at home as the home team. however, the probability of PSG and Benfica is unlikely to give the home team an easy win. and if, we refer to the odds provided by the bookie. as you said, PSG and Bencifa will determine the first place as the leader of this group.
So the opportunity for Juventus to get to the Europa League, inevitably has to beat PSG. however, it seems difficult considering there are 11 Juventus players who have been injured. in the end, Juventus' hope was in Bencifa.
With a result like that, Barcelona has been confirmed for the Europa League. I think Barcelona is the only team from the Champions League that has a chance to get to the semi-finals and or the final of the Europa League this season. Because for the other teams I think they are still very messed up, even though they will play in the Europa League but it doesn't guarantee the teams from the Champions League will easily get a win. Because the teams in the Europa League have also looked better so far like for example Arsenal, Manchester United, Betis and also Freiburg and there are several other teams that I think at this moment the Europa League teams cannot be underestimated at all.
Barcelona has ensured its ticket to the Europa League. but yes, we agree. there is no guarantee, Xavi Hernandez's team can walk smoothly to the final match later. to be sure, there are other formidable teams here that have existed before. I am still optimistic, Arsenal will remain a strong contender in this competition.
