I like your 2line parlay, but I'd think Napoli/Atletico parlay looks surer than Napoli/Juventus. Juventus have a curious way of drawing games in which they're favorites of this magnitude. You saw how the Liverpool and Inter Milan games ended in draws yesterday!
Too bad even Atletico lost.
Between Juventus and Fiorentina, I expect one to either lose or draw. Avoid laying huge favorites in all leagues these days. For such games, you may just limit your play to o/u.
