There's a mountain to climb for the hosts AIK after their 2-0 defeat at Celtic Park last week.
An away goal for Neil Lennon's travelling Celtic would all but confirm their place through this tie, given AIK would need to score at least four goals in reply.
Celtic have generally been in very good form this season, with the big outlier the defensive capitulation that saw them lose 4-3 at home to Cluj, their hopes of Champions League football going with it.
They've won eight of their other ten competitive games so far this season, including every game so far in the league, with victories including a 7-0 victory over St. Johnstone and a 5-2 victory over Motherwell.
AIK tend to have more low-scoring games, especially of late. There have been less than three goals in six of their last seven matches in all competitions, although their domestic form is strong - they're currently fighting for the title, 21 games into the Swedish season. They're four points off the top spot, but they've also won six of their last seven games.
Celtic might have one eye on Sunday's match against Rangers, the first Old Firm of the season, but we still expect a strong team to finish the job here, in a repeat of last week's tie. Back them for a win and clean sheet.
