Into the last five at the Emirates. As sedate as a European game gets.

Celtic 0-2 Salzburg

Quote MessageHowler. I can't say much more than that. Craig Gordon will know that. It's a lack of concentration, of not knowing where his man is, and he's cost his side.
Celtic 0-2 RB Salzburg
Celtic need two goals in eight minutes, or for Rosenborg to find an equaliser against Leipzig...
Olympiakos 3-1 AC Milan
Kostas Fortounis has put Olympiakos 3-1 in front from the penalty spot!
Incredible scenes in Greece and it means the hosts are going through as it stands...
Arsenal 1-0 Qarabag
Into the last 10 minutes at Arsenal.
Fredrik Gulbrandsen (77 mins)
Oh noooo....
He's been excellent all night but that is a real horror show from Craig Gordon. Loris Karius style.
He tries to throw the ball out quickly, and Fredrik Gulbrandsen is right there, inches from his face. It hits Gulbrandsen on the heel, and he has an open goal to tap it into.

Paul: I hope Elneny and his sideways and backward passing hasn't got ambitions of being a first team regular anytime soon. He will never displace Xhaka or Torreira.
Kyle: No more than Salzburg deserve they wouldn't look out of place in the Champions League they've been excellent and could go on and score another goal or 2 and finish the job in style. Celtic are ordinary at best.
Arsenal 1-0 Qarabag
Well, that was almost brilliant.
Eddie Nketiah carries the ball a good 45 yards up the pitch before he just falls over his own feet a touch at the last minute.
He spreads it out wide though, Bukayo Saka skips past a defender and throws in a lovely cross with his left foot, Nketiah gets on it and heads home.
Offside though. And he was...

Salzburg are very good, but this is an awful performance from Celtic. Really surprised.
Olympiakos 2-1 AC Milan
Olympiakos moved into second spot momentarily as they doubled their lead through Cristian Zapata's own goal.
But AC Milan pulled one back within seconds as Zapata made amends down the other end.
The Greek side need another goal now or Milan are going through.
Arsenal 1-0 Qarabag
It's been a bit like his own testimonial, and Laurent Koscielny is applauded off after 70 minues on his return. Nacho Monreal comes on for the last knockings.
Arsenal 1-0 Qarabag
Bukayo Saka has another shot on target, easily saved but he looks a bag of tricks this lad. Get him out on loan.
Munas Dabbur (67 mins)
It has been coming, but that's a blow. Celtic are going OUT as it stands. Munas Dabbur heads home.
Arsenal 1-0 Qarabag
Well there's been nothing happening in the half at all but all of a sudden a sensational run from Ainsley Maitland-Niles, who has moved into midfield, cuts Qarabag open. He lays it back for Bukayo Saka, but his shot is deflected away for a corner.
Saka then tees up Mesut Ozil, but his shot is charged down.
Arsenal 1-0 Qarabag
Alexandre Lacazette is excused, off he comes for the last half hour. Arsenal send on centre-back Zech Medley so there will be a reshuffle. Not that it really matters.
Olympiakos 1-0 AC Milan
Olympiakos have gone in front against AC Milan.
Pape Abou Cisse's goal means the Greek side need just one more goal to go through at the Italian giants' expense.
Just under half an hour left in that one.
Arsenal 1-0 Qarabag
Half an hour left of this very strange game of football.
Arsenal 1-0 Qarabag
A very rare chance for Qarabag - Emiliano Martinez in the Arsenal goal comes for a corner, doesn't get there, and it's headed over the top by Donald Guerrier.

Seriously good Salzburg side, this. Champions League level. Celtic not getting close to them in midfield. Loads of space. Big job ahead.
Arsenal 1-0 Qarabag
Mesut Ozil's face is a picture. He puts a free-kick on the head of Sokratis, and the former Dortmund man screws a header absolutely miles wide. Yards, yards, yards wide.
