Qualifying for the next round is almost impossible for Juventus. Because Juventus have lost three out of four matches. And now they are 5 points behind second placed Benfica in the table. Benfica can only qualify for the next round if they manage to draw one of their next two matches. Benfica will play against Juventus and Maccabi Haifa in the next two matches. It will not be difficult for Benfica to get 1 point in these two matches. Because they are in pretty good form now. And Juventus will face PSG in their last match. It will be very difficult for Juventus to get 3 points against PSG.
Juventus chance qualifying to next round quite heavy behind 5 points left from PSG and Benfica, actually if win from Benfica and PSG still not guarantee qualifying to next round depending with Benfica vs Maccabi Haifa and PSG vs Maccabi Haifa matches. Juventus can get 9 points maximum if want 2 match later but Benfica can get 11 points although loss from Juventus but can win from Maccabi Haifa in the last match. Juventus really need help from Maccabi Haifa to win at one of two match left between PSG or Benfica.
Honestly? I think they would do much better in europa league. Now I know that if you go up a stage in UCL that means more money, but it also depends on the long run results. If you asked me if I would rather go up a stage and lose there versus being in semi-finals of Europa, I would pick semi finals, or even winning it, but if they are going to be in quarter finals of UCL or just lose the next game on Europa as well, then it's of course better to be in UCL instead.
I believe they are going to face easier opponents in Europa, looking at how they are not doing that great neither in league nor in UCL, I could see them doing a lot better in a lower level.
