Follow Mail Sport's live blog for the latest score, team news and updates as Union Saint-Gilloise host Liverpool in the Europa League plus updates from Zrinjski Mostar's clash with Aston Villa.
So, are Aston Villa safe and dry?
You might think that if Aston Villa are in the top two of their group that they automatically get through to the last 16 of the Europa Conference League, but that isn't the case!
Yes, they're through the group, but if they finish second behind Legia Warsaw, they will have a play-off against one of the Europa League drop-down teams who finished third in their group.
A point tonight will do.
GO DEEPER: the lowdown on Ben Doak and other youngsters
Ben Doak has been described by Virgil van Dijk as a 'Tasmanian Devil'.
Van Dijk had high praise for the 18-year-old: 'He’s very exciting, very direct, one-on-one.'
And how about Jurgen Klopp? He said: 'Ben is a special boy. He is really confident and has something nobody else delivers.'
He's made four outings this season, but in case you're not familiar with one of the club's hottest prospects, here is Lewis Steele's piece on him and some of the starlets set for minutes tonight.
A closer look at tonight's venues
Only an hour to go until kick-off, folks!
Moises Caicedo: Liverpool arrived 'too late' for me
We heard enough in the summer that Moises Caicedo idolised Chelsea since a young age - there was that old picture of him sat in a car boot wearing a Blues kit alongside his mother.
Lots of Liverpool fans were gutted to miss out on the young midfielder, but... well, it hasn't turned out too badly so far, has it?
WATCH: Jurgen Klopp's thoughts on Union Saint-Gilloise
Aston Villa's line-up is out!
It's a fairly seasoned line-up from Aston Villa tonight with some big hitters including Douglas Luiz, Moussa Diaby, and a solid defence.
But young goalkeeper Filip Marschall is given a shot between the sticks with Robin Olsen unavailable.
Jacob Ramsey makes his first start since returning from injury.
Liverpool release line-up full of youngsters!
Well, it IS a night for youth as we expected.
Harvey Elliott, Callum Chambers, Ben Doak, Kaide Gordon, Jarell Quansah, Conor Bradley, and Curtis Jones - of varying levels of experience - are all given the nod.
Which Liverpool youngsters could we see in action?
Jurgen Klopp knows the importance of rotating his side, particularly with a match against Manchester United beckoning on Sunday.
Could this be a night for Ben Doak on the wing and Callum Chambers in left-back?
Maybe even a Kaide Gordon, the winger who has returned from 19 months in the injury underworld? He's clearly got perseverance.
Jarell Quansah and Harvey Elliott, who are more established, will also fancy themselves.
Who do you want to see tonight, Reds fans?
Beautiful surroundings for a European jaunt!
Even Birmingham's most ardent fans might envy views like this!
But Aston Villa would do well not to get caught up in the historic sights.
Zrinjski Mostar claimed a 4-3 win over AZ Alkmaar earlier in the group stages. Not a bad scalp.
Good evening!
Hello and welcome to Mail Sport's live blog of Thursday's 5.45pm European action!
Tonight sees Liverpool visit Union Saint-Gilloise in the Europa League, though they're playing at Anderlecht's Lotto Park.

Both English sides have already made it out of the groups, but it's still sure to be a fascinating night!
We'll have separate coverage of West Ham later.
