Benfica managed to qualify for the knockout round despite having a strong team like Juventus in the group. I think they are happy with that. Benfica's performance was very good. They did not lose even one of the 5 matches. They had a very good performance.
But I don't think they are too keen to go top of the table. They are still 4 goals behind PSG. But Benfica has a chance to top the table. Because PSG's opponent Juventus' performance in the last match was erratic, but they are not weak. It is also difficult to predict that PSG will definitely win this match. If somehow PSG lose or draw, and Benfica manage to get full points against Maccabi Haifa, PSG will move into second place in the table.
