Top spot in Champions League Group B is at stake when VfL Wolfsburg host Manchester United at the Volkswagen Arena on Tuesday evening.
If either club wins the match in Germany they will finish the round as group leaders, the position currently held by Wolfsburg with United just a point behind.
But both sides must also be wary of PSV Eindhoven, who could sneak through with victory over CSKA Moscow. Should the Dutch side win, a draw would be good enough for the Germans but not for United.
The Red Devils are undefeated in their last seven Premier League matches although they have drawn their last three against Leicester City, West Ham and PSV. But United will take confidence from their 2-1 victory over Die Wolfe earlier in the group stage.
Wolfsburg have had mixed results of late, and enter the match off a 2-1 loss to BVB Dortmund in the Bundesliga that left them fifth in the standings. But they crucially lead the group after beating CSKA in the previous round, giving them the advantage heading into the crucial final round.
United boss Louis van Gaal has had to leave seven injury victims behind for the trip, including Wayne Rooney (ankle), Morgan Schneiderlin (hip/thigh), Ander Herrera (hamstring), Phil Jones (ankle), Marcos Rojo (dislocated shoulder), Antonio Valencia (ankle) and Luke Shaw (broken leg).
Wolfsburg, meanwhile, will have Dante available again after serving suspension, but Luiz Gustavo and Ricardo Rodriguez are injury doubts.
