It is another big night for Mauricio Pochettino and Tottenham.
The Champions League returns to Tottenham Hotspur Stadium and Spurs know that three points are a must to get their campaign back on track.
After letting slip a 2-0 lead against Olympiacos in Athens, Spurs were thrashed 7-2 by Bayern Munich at the start of a horrendous week prior to the international break.
That's one point from two games and defeat to Red Star Belgrade, also known as FK Crvena Zvezda, will leave them five points adrift of the top two qualifying spots with only three games to play.
Crucially, two of those remaining three games will be away from home.
Tottenham came back from a similar position last year, and famously went on to reach the Champions League final, but their form so far this season does not suggest they would be capable of overturning such a deficit this time around.
A draw with Watford on Saturday was not what was required in the Premier League, but they did show some fight in the latter stages of the match to secure a point.
And they will need to be at it from the word go against Red Star.
Manager Mauricio Pochettino has said: "The most important thing is to understand that we need to give our best, be solid and be strong and focused and concentrated, because when all the circumstances are against you, the most important thing is to be strong.
"You need to expend more energy. Yes we know the situation is all about games and time, be solid, train, never give up, and be focused on your work and improving. And be able to win."
Pochettino is expected to make changes for the match, but who will be dropped after a poor run of form and who will get to battle on?
We asked you, the fans, to name your team for the Champions League clash.
And above is the team you would go with, made up of the votes from everyone who put a team together.
That suggests you would like the boss to make four changes, with both full-backs changing and giving Tanguy Ndombele and Son Heung-min starts after coming off the bench on Saturday.
