Celtic boss Ange Postecoglou will have marked his starting line-up in pencil but unlikely be able to firm it up in pen until he finds out if Jota has made it.
Joe Hart, Josip Juranovic, Cameron Carter-Vickers, Greg Taylor, Reo Hatate, Matt O'Riley and Liel Abada appear cast-iron starters. And it's likely Kyogo edges out Giorgos Giakoumakis up top, while Moritz Jenz and Stephen Welsh battle it out to partner Carter-Vickers. But the major questions centre around two key positions and how you replace key men Callum McGregor and Jota?
The latter may make it but it still leaves the Australian with some thinking to do how to best take on Marco Rose's men and secure a signature Champions League night and turbo charge the Hoops' hopes of reaching the last 16. Celtic had their moments before Leipzig outgunned them in the second half last week.
