Brendan Rodgers has named his Celtic starting XI to take on Lazio this evening.
Matchday five of the Champions League group stage gets underway at 5.45pm UK time.
It's a tough trip to Rome for the Hoops, who prop up Group E heading into the game.
The task is simple - win, or Celtic are out of Europe after Christmas.
Here's how Rodgers has set his team up for this crucial encounter...
LAZIO XI: Provedel, Patric, Felipe Anderson, Guendouzi, Luis Alberto, Isaksen, Castellanos, Lazzari, Mario Gila, Rovella, Marusic.
Subs: Sepe, Magro, Pellegrini, Kamada, Pedro Rodriguez, Immobile, Hysaj, Cataldi, Ruggeri
CELTIC XI: Hart, A. Johnston, Carter-Vickers, Scales, Taylor, McGregor, O'Riley, Bernardo, Forrest, Kyogo, Yang.
Subs: Bain, Morrison, Lagerbielke, Phillips, Turnbull, Holm, Oh, Ralston, Welsh, Frame, M. Johnston
Celtic are "interested" in a move for Estoril star Tiago Araujo in the January transfer window.
This is according to the Daily Telegraph who claim the Hoops are considering a deal of around £4million for the player.
Araujo is capable of playing in a variety of positions such as left-back and in midfield.
He has featured 16 times this season, scoring twice and providing three assists.
The 22-year-old is under contract at Estoril until 2025 and could provide competition for Greg Taylor with Alexandro Bernabei out of the picture at Parkhead.
He came through the ranks at Benfica but left the Portuguese giants last summer
