Following their dramatic victory over Croatia on Friday, Scotland can still qualify from their Nations League group tonight.
The Scots need to defeat Poland and hope that Portugal beat Croatia in the other fixture, while they need a swing of goals in their favour also.
Here's how the Poland and Scotland squads are shaping up.
Poland Team News
Poland will be missing their best player as Barcelona striker Robert Lewandowski is out due to a back injury.
Arkadiusz Milik is also injured, so Karol Swiderski and Mateusz Bogusz will contest for the spot up top alongside Krzysztof Piatek.
Pawel Dawidowicz isn't in the squad.
We could see some rotation from Michał Probierz as Poland were demolished 5-1 by Portugal a few days ago.

Scotland Team News
Angus Gunn, Aaron Hickey, James Forrest, Che Adams and Lewis Morgan are out due to injury, but McGinn and Stuart Armstrong are back in the squad, with the former coming off the bench to score the winner on Friday.
The Aston Villa midfielder is still looking for full fitness, so he may start the game on the bench again.
Tommy Conway started up top on Friday but was eventually replaced by Lyndon Dykes, so that might be a change we'll see to the starting XI from Steve Clarke.
