The Scottish champions now know the eight sides they could meet for a place in the Champions League league phase after the conclusion of the second qualifying round. They enter the champions path as a seeded team for Monday's draw.
Celtic's campaign last season ended in a dramatic penalty shootout defeat to Kairat Almaty, and they could face the Kazakh side again. Levski Sofia also advanced after beating Craiova 3-2 on aggregate, while Kairat overcame Omonoia on penalties.
Draw shake-up after AEK switch
A dramatic night in Poland saw AEK move to the champions path at the expense of Lech Poznan. The Polish side collapsed to a 4-1 home defeat after a 4-1 first-leg advantage against Aarhus, losing on penalties. This meant Celtic dodged a clash with the Greek champions.
Aarhus now go into the hat alongside Azerbaijani side Sabah. Slovenian champions NK Celje and Ararat-Armenia also qualified, with Celje beating Egnatia on penalties and Ararat edging Shamrock Rovers in Dublin.
Unseeded sides confirmed
LASK Linz, despite finishing second in Austria behind Sturm Graz and ten points clear of Red Bull Salzburg, enter as an unseeded team. Viking Stavanger also goes unseeded after winning the Norwegian league for the first time in 34 years.
