Celtic booked their place in Friday's draw for the Champions League play-offs with a 0-0 draw against Qarabag in Baku on Wednesday evening.
Ronny Deila's men led 1-0 from the first leg at Parkhead and keeper Craig Gordon made a terrific save in the first half to preserve their advantage.
Celtic defended stoutly in the second period and almost snatched victory in the closing minutes when Stefan Johansen fired just wide.
Their potential opponents in the next round are Skenderbeu Korce (Albania), Maccabi Tel Aviv (Israel), Astana (Kazakhstan), Partizan Belgrade (Serbia) and Malmo (Sweden).
