Celtic have the chance to clinch a place in the last 32 of the Europa League when they face Salzburg at Parkhead on Thursday evening.
The match is live on BT Sport, kick-off 8.05pm, and a win will guarantee that Ronny Deila's team reach the knock-out stage with a game to spare.
Even if Celtic lose tonight they will progress unless Dinamo Zagreb - who they play in Croatia on December 11 - beat Astra in Romania.
The Scottish Premiership leaders have won both home games so far and drew 2-2 away to Salzburg, who have already qualified, on matchday one.
Deila told the club website: "We are in the position we deserve to be. We have eight points now and that’s a fantastic position.
“I think we are seeing improvement in our last matches but we are looking for a higher level and Salzburg will be a big test for us.
“I hope Craig Gordon won’t be so important this time but he’s been fantastic the whole season and he is a great goalkeeper."
