Newcastle boss Eddie Howe has admitted tonight's Champions League clash against Paris Saint Germain is a pivotal moment in their season.
They're bottom of their group ahead of the game in the French capital.
That Group F game kicks-off at 8-o'clock while at the same time AC Milan host Dortmund.
Champions Manchester City can secure top spot in Group G with a win over RB Leipzig at the Etihad.
That also kicks-off at 8.
Before that, Celtic will once again look for their first win in Group E when they go to Lazio for a 5.45pm start.
