Atalanta are the only Italian side in the Europa League Round of 16 and could face Lyon, Bayer Leverkusen, Galatasaray, Monaco or West Ham.
La Dea swept Olympiacos aside 3-0 in Athens this evening, 5-1 on aggregate, to secure their place in the next phase of the tournament.
Lazio were eliminated by FC Porto and Napoli crushed by Barcelona, so Atalanta remain the only Serie A representatives in this tournament.
The draw for the Round of 16 will be held in Nyon on Friday at 11.00 GMT, with eight group winners as top seeds and the eight play-off victors unseeded.
That means Atalanta will face a difficult test, as options include Eintracht Frankfurt, Galatasaray, Bayer Leverkusen, Lyon, Monaco and West Ham United.
