Without a win in his first three games in charge, Ange Postecoglou could really do with getting a victory in the Czech Republic.
Knocked out of the Champions League and having been beaten by Hearts in the opening game of the league season, it's been a bit miserable so far for Hoops fans.
Jablonec are up next and Joe Hart could make his debut between the sticks and that should instantly give the Celtic defence a bit of a confidence boost.
Reaching the Europa League group stage will be a huge target for Postecoglou now but while the Aussie wants to play a particular brand of football, he might be desperate for the scrappiest of 1-0 victory just to get a win on the board.
Here's all you need to know about the game.
When is kick-off?
Celtic are in the Czech Republic for the for the first leg of their Europa League tie with Jablonec.
Kick-off is at 4.45pm at the Stadion Strelnice.
Who is the referee?
Turkish referee Halil Umut Meler is the man in the middle for this game.
He’s assisted by Mustafa Eyisoy and Cevdet Komurcouoglu, with Arda Kardesler as the four official.
The whistler handed out five yellow cards in his only game so far this season, a 2-1 win over Kairat Almaty against Red Star Belgrade.
He appears to be a bit of a card happy ref, with 128 yellows and eight reds in his 30 games last season.
That includes 10 yellows and one red in a match between Ankaragucu and Galatasaray in March.
Is it on TV?
Yes. The game is being shown live on BBC Scotland. The programme begins at 4.30pm, just 15 minutes before kick-off.

Yes. You'll be able to stream the game live on the BBC iPlayer.
Prediction
Celtic have really struggled so far this season but with the addition of Joe Hart in goals and Carl Starfelt having had 90 minutes under his belt, you'd expect them to beat the Czech side. Prediction: Jablonec 0 Celtic 2.
