Simply for Tottenham, win, and they're through. Win, and they will get to be managed by Antonio Conte in the Champions League knock-out stages for the first time. Win, and they escape, free to leave behind the turbulence of a hectic group stage.
After opening the campaign with a victory over Marseille, the repeat will ensure their passage to the next round. They currently sit top of the group on eight points, but all four teams could yet finish in all four places. It's not one for the faint-hearted, especially as they now have to do it away from home.
Had the late goal against Sporting Lisbon counted last week, the progression would have been secured already, and it would have been a relatively relaxing situation.

That isn't the case though, and it will be a nervous watch, especially as Spurs have gone behind first in three of their five European matches so far and drew another 0-0. If they have to do this coming from behind again, it may be a tough watch for nervous supporters that haven't seen their team progress past the round of 16 since 2019.
