22:51 CET - Celtic's humiliation is finally over in Germany as magnificent Borussia Dortmund hammered the Scottish side 7-1. A hat-trick from Karim Adeyemi was the standout part of a dominant performance from the hosts.

22:49 CET - We won't in the Slovak capital as Manchester City have wrapped up a 4-0 victory over a valiant Slovan Bratislava.
Read the report from that game now.
22:48 CET - Into the final few minutes, will we see any late goals?

22:39 CET - More second-half success for Inter as Mehdi Taremi strokes home a penalty to finish the game off at the San Siro against Crvena Zvezda. Barcelona are also extending their lead to five, this time through an own goal from Young Boys' Mohamed Camara.
22:37 CET - Celtic fans, you don't need to read this update... Felix Nmecha has come off the bench to make it 7-1 with 10 minutes still to play. What's German for cricket score?
At least Karim Adeyemi is off the pitch.
22:31 CET - A proud moment for Manchester City academy graduate James McAtee, as he scores his first goal for the club to make it 4-0 to the Citizens over Slovan Bratislava.
22:29 CET - It's Lautaro Martinez's turn to get on the scoresheet for Inter, seeing their lead go out to three over Crvena Zvezda as the hosts capitalise on a defensive mistake to score.
22:23 CET - PSG have not had the most productive night against Arsenal, seeing themselves currently two down in London. But, they are showing signs of promise, hitting the bar from a corner with David Raya beaten. Their fans, on the other hand, are bringing the noise tonight.
Productive is certainly the word to describe Borussia Dortmund though, they are now 6-1 up against Celtic as Serhou Guirassy adds his second of the game. Could be a fight for the match ball later tonight...
22:17 CET - Marko Arnautovic has doubled the advantage for Inter at the San Siro against Serbian side Crvena Zvezda, giving the reigning Serie A champions a decent grip of the match.
22:15 CET - It's inevitable, isn't it? Erling Haaland bursts away from the Slovan Bratislava defence, rounds the keeper and tucks home another goal for the season. Manchester City now 3-0 up in the Slovak capital. The Norwegian now has more Champions League goals (42) than appearances (41). Remarkable.
22:09 CET - Barcelona are cruising now against Young Boys, banging in their fourth of the night - Robert Lewandowski adding to his tally six minutes into the second half.
Meanwhile, Victor Boniface has his first Champions League goal for Bayer Leverkusen as they take a 1-0 lead over AC Milan.
22:01 CET - We are back underway in the second half of tonight's Champions League ties!
21:55 CET - The big story so far though has to be Karim Adeyemi's first-half performance against Celtic. The German forward has three goals to his name already as Borussia Dortmund steamrollered their Scottish opponents.
A warning shot for teams around Europe?
21:50 CET - Phew, let's take stock after a raft of goals across Europe - 15 to be precise.
Slovan Bratislava 0 Manchester City 2
21:40 CET - Is it all over in Dortmund already? Serhou Guirassy nets his side's fourth of the first half from the penalty spot as they seem out of sight of Celtic. It definitely is now, as two minutes later, Karim Adeyemi completes a brilliant first-half hat-trick to compound the misery of the Scottish side further.
21:38 CET - It's gone from bad to worse for Swiss side Young Boys as Barcelona defender Inigo Martinez pops up with a rare goal to put his side 3-0 up just before half-time. A big moment for the Spanish centre-back, his first goal in the Champions League.
Pedri is having a masterclass of a first half - here is his pass map.
21:34 CET - Over to Spain, where Barcelona have doubled their advantage over Young Boys - Raphinha getting himself on the scoresheet in the 34th minute. Meanwhile, in London, Arsenal are also two to the good against PSG, Thomas Partey with the goal from a teasing Bukayo Saka free-kick. By all accounts, the hosts are good value for their lead.
21:29 CET - It's a second of the night for the ever-threatening Karim Adeyemi, giving Borussia Dortmund a 3-1 lead over Celtic at Signal Iduna Park with an absolute screamer. He finds the top corner from a very tight angle to give his side a two-goal cushion.

Elsewhere, Inter have put themselves a goal to the good at San Siro in their match with Crvena Zvezda thanks to Hakan Calhanoglu.

Meanwhile, PSV lead Sporting after 15 minutes through Dutch international Jerdy Schouten.
21:11 CET - Borussia Dortmund are head again, this time through Karim Adeyemi - the third goal in the first 12 minutes in their match against Celtic. Steady on, lads.
21:10 CET - GOALS, GOALS, GOALS! In Bratislava, Manchester City have taken the lead through a deflected shot from Ilkay Gundogan - his first goal for the club since returning from Barcelona - whilst his former club lead Young Boys 1-0 through old faithful Robert Lewandowski.

20:21 CET - What a dream night for Brest! Their best goal of the night sees Mathias Pereira Lage curl an effort in from the edge of the box to put this match beyond doubt and don't they know it - the whole squad mobs the Frenchman to celebrate. A clinical performance from the Ligue 1 side.
20:16 CET - It gets better and better for Brest as Abdallah Sima reacts first on the rebound to score his second of the night against Salzburg to put his side 3-0 up. Boos and whistles ring around the stadium, the home fans frustrated with the display.
20:11 CET - Still all square between Stuttgart and Sparta Prague and the second half is following the pattern of the first with both teams creating chances aplenty.
The same can't be said in Salzburg, where Brest have doubled their lead in the 66th minute through a nice strike from Mahdi Camara after a bit of fortune to see the ball at his feet in the box. A mountain to climb for the Austrians now.
