Apart from Napoli, if I interpret it correctly, all Italian teams are through to the round of 32.
And for them beating Bratislava, who atm have a grand total of 0 points shouldn't be anything else than a formality either.
Napoli are through (they can lose their last match), because they win on H2H against Sparta and Young Boys, and the last match is played between Sparta and Young boys, if Sparta wins, then Sparta is 1st with 13 points, Napoli 2nd with 10 points and Young Boys 3th with 9 points. If the game ends in a draw, then Sparta is first with 11 Napoli and Boys both have 10, but Napoli have a better H2H. And if Young Boys win, then they will finish 1st with 12 points, Napoli will be 2nd with 10 and Sparta will be 3th with 10 points, but again Napoli win on H2H
So Torino are the only team that aren't already through.
