It's a tie that should be all but over after three away goals but Celtic can't rest on their laurels against Sarajevo.
Neil Lennon will be confident his side can progress to the second round of qualifying where they will face a trip to Estonia.
Sarajevo are no mugs though and showed they can be a threat with their fast start in the first leg last week.
The Hoops will be without Mikey Johnston after his stunning strike last week but Christopher Jullien could make his competitive debut. The Frenchman certainly looked the part during Saturday's friendly with Rennes.
Odsonne Edouard is likely to lead the line again but Leigh Griffiths will be aiming to make his competitive return to action after his time off for personal reasons.
Boli Bolingoli is the only other injury doubt but the jet-heeled left-back is expected to be fit enough to take his place in the starting XI.
Celtic know they will face Nomme Kalju if they see off their rivals next week in front a big Parkhead audience.
We'll have full team news, action and reaction from the clash right here.
Jozo Simunovic backs Parkhead atmosphere to give Hoops the edge
We’re set for another magical European night at Celtic Park, and Jozo Simunovic reckons the raucous atmosphere could spur his side onto success once again.
“The noise on European nights at Celtic Park is amazing, and no matter how many times you play in these games, it always catches you by surprise.
“Every game is something different, and there are different things at stake. One thing is constant, though, and that’s what it means to the fans, the players, the backroom staff, the media. The noise is what makes European competition and nothing compares to Celtic Park.”
Ajer expects a challenge
Celtic might have been convincing in the first leg, returning to Parkhead with three away goals and a two goal cushion, but Kristoffer Ajer says they can take nothing for granted against the Bosnian champions.
“We expect another tough game. They played a really good game over there, but we came away with a strong result. We still need to do a job tonight.
“Celtic want to get to the Champions League every single year and that’s our main target. We take it one game at a time and hopefully we can do it.”
