A draw would be enough for Tottenham to qualify from a perilously set-up Group D on the final day of Champions League action.
Antonio Conte's men currently sit top on eight points but are just two clear of bottom-side Marseille, who will be desperate for the victory that would likely eliminate Spurs from the competition. It really is all to play for.
With the stakes so high, here's the lineup Conte could select.

Tottenham predicted lineup vs Marseille (3-4-2-1)
GK: Hugo Lloris - One of Lloris' two European clean sheets this season came in the victory over Marseille in the first game of the campaign.
CB: Davinson Sanchez - Cristian Romero missed training on Monday, indicating that his absence from the game against Bournemouth was not a one-off.
CB: Eric Dier - Conte wanted to rest Dier against Bournemouth but had to bring him off the bench to stop things from going completely awry.
CB: Clement Lenglet - Lenglet looks to have squeezed this last spot away from Ben Davies and his big-game experience should help him keep his place.
RM: Matt Doherty - After starting the season out in the cold, Doherty appears to have wrestled his place away from the inconsistent Emerson Royal.
CM: Pierre-Emile Hojbjerg - The Dane has been one of Tottenham's top performers this season and will likely be one of the first names on Conte's team sheet.
CM: Rodrigo Bentancur - Bentancur saved the day against Bournemouth with the latest of late winners. He'll start in the usual two-man midfield, after the 3-5-2 failed to impress.
LM: Ivan Perisic - Ryan Sessegnon bagged a goal against Bournemouth but Perisic's experience in these high-pressure games will work in his favour.
AM: Lucas Moura - Bryan Gil feels more like a sparkplug substitution late in games so expect Conte to turn to Lucas.
AM: Son Heung-min - Son is back on a goal drought, scoring in just one of his last eight outings in all competitions.
ST: Harry Kane - Kane has had no such struggles in front of goal although he has drawn a blank in four of his five Champions League outings this year.
