23:35 CET - That's all from us tonight on the Football Tracker, but be sure to tune in again tomorrow as the Champions League action continues with nine more matches!
Check out the UCL fixtures and standings here.
23:02 CET - All of the matches have now wrapped up and the headline results are that 10-man Bayern Munich have hung on to beat PSG 2-1 away in Paris, while a resurgent Liverpool have edged Real Madrid 1-0 at Anfield.
Elsewhere, Tottenham scored four in their big win, with Atletico Madrid also victorious. Check out all the late kick-off results below:
Atletico Madrid 3-1 Royale Union SG
22:51 CET - PSV have scored a late, late leveller against Olympiacos, 1-1 down in Greece and almost over.
22:50 CET - We are heading into stoppage time around the grounds...
22:39 CET - PSG have pulled a goal back against 10-man Bayern, thanks to Joao Neves. It's 2-1 to the Bavarians in the French capital, and there's still plenty of time.
22:33 CET - Moving over to Madrid, Atleti have doubled their lead (2-0) against Royale Union Saint-Gilloise, with Conor Gallagher absolutely smashing the ball home from inside the box.
22:26 CET - Make that 4-0 to 10-man Spurs... wow. Tottenham Hotspur Stadium is rocking!
22:22 CET - Liverpool have broken the deadlock against Real Madrid, it's 1-0 to the hosts at Anfield, thanks to an Alexis Mac Allister bullet header off a free-kick routine. Of all the men, it had to be the smallest one on pitch!
Spurs have also scored, despite being a man down, to lead Copenhagen 3-0. Micky van de Ven has scored one of the greatest goals you will see a centre-back score! He's picked up the ball at his own box, run the length of the field and slotted it brilliantly... Incredible stuff from the flying Dutchman.
22:15 CET - Just after going 2-0 up, Spurs are now down to 10 men! Just like Bayern, funnily enough. First goal scorer Brennan Johnson has been shown a straight red after a VAR review... Could Copenhagen turn this one around?
22:08 CET - We are back underway around the grounds, and Spurs have scored the first goal of the second halves, going 2-0 up against FC Copenhagen through Wilson Odobert.
21:48 CET - The half-time whistle has blown across Europe, with the standout scoreline coming in the French capital, where Bayern lead by two and could quite easily have scored more. But... their double goalscorer, Luis Diaz, has been sent off on the stroke of the break!
Juventus, Monaco and Atletico Madrid all got goals shortly before the break.
Here are the scores:
21:38 CET - In a big blow for PSG, Dembele has picked up yet another injury and has had to go off.
It's not going the reigning champions' way tonight.
21:34 CET - Diaz does it again! The Colombian has doubled Bayern's lead, shortly after Ousmane Dembele had a goal disallowed for offside.
At Anfield, meanwhile, the hosts felt they should have had a penalty, but the referee decided otherwise after checking the monitor. Real Madrid are controlling possession, but Liverpool are looking more dangerous.
21:19 CET - It's been a fast start to the night, with Sporting, Olympiacos and Tottenham all taking early leads.
21:07 CET - Bayern strike first in Paris! Luis Diaz has put them ahead after just four minutes, tapping in a rebound from a Michael Olise effort.
20:52 CET - Our attention now turns to a mouth-watering selection of late-night action, with the clashes in Liverpool and Paris promising to be two of the best of the season so far.
We'll provide key updates here, and you can follow every kick at the links below:
20:46 CET - Despite some early pressure from Slavia Prague, Arsenal have continued their perfect start to the Champions League season, winning 3-0 thanks to a penalty from Bukayo Saka and a second-half brace from Mikel Merino. It was a clinical display from the Gunners, who recorded their eighth-straight clean sheet. The last time the defence was breached back in September, and right now, this streak could go on for some time.
For the home side, they were valiant throughout and battled hard, but that extra quality that comes when playing a Premier League side told in the end. Could Arsenal be a real contender for the Champions League this season?

20:42 CET - The Italian champions are held! Despite dominating possession, Napoli have taken just a point at home to Frankfurt, with the German side defending well and riding their luck at times to earn a 0-0 draw.
20:34 CET - What a night for Max Dowman! At just 15 years and 308 days, the teenager's appearance at Fortuna Arena means he has become the youngest-ever player in a Champions League game. It's an incredible achievement.
However, he can only watch on as Ben White gives away a penalty. Slavia Prague look ready to break Arsenal's goalless run, but VAR overturns the decision and it remains 3-0.

20:26 CET - A bit of history has been made in Prague, where Arsenal's Max Dowman has become the youngest player to ever play in the Champions League at the age of 15.
20:23 CET - Napoli are running out of time in their quest to get their second Champions League win of the season, with Frankfurt holding firm in Italy.
20:18 CET - Arsenal have made it 3-0 in Prague to wrap up the three points.
Despite some Slavia pressure, Arsenal have their third of the night through Mikel Merino. Home goalkeeper Jakub Markovic misjudges the flight of a lofted pass, opting to catch rather than punch, and it lands straight onto the Spaniard's head. He doesn't know too much about it, but the ball ends up in the back of the net. The Gunners look home and hosed.

20:07 CET - Over in Paris, Ousmane Dembele is making his first Champions League start of the season, with both PSG and Bayern close to full strength.
19:57 CET - It's 2-0 in Prague!
Who needs Viktor Gyokeres? Just as you were starting to question Mikel Arteta's decision to start Mikel Merino - absent apart from his yellow card in the first half - the Spaniard pops up in the first minute of the second half to net the visitor's second after good play from both Declan Rice and Leandro Trossard. It's a mountain to climb for Slavia Prague now.

19:53 CET - The big news coming out of Anfield is that Florian Wirtz is starting for Liverpool, with the German replacing Cody Gakpo. As expected, Trent Alexander-Arnold is on the bench for Real Madrid.
19:39 CET - It's half-time in Prague, so here's the latest from our reporter, Josh Donaldson, at Fortuna Arena:
Slavia and Arsenal's players exit the field at half-time to a wall of noise from the home fans. It's been an intense atmosphere so far, normal for those who frequent Fortuna Arena regularly, but the 19,703-seater has lifted their team to be on level par for much of the first 45 against the Gunners.
They may be behind 1-0 to Saka's spot-kick, but the home fans will be buoyed by their players' willingness to chase and harry. They have missed an end product, but this well-drilled team under Jindrich Trpisovsky are holding their own.
Meanwhile, in Naples, there's nothing to separate Napoli and Frankfurt, with Antonio Conte's side edging a closely fought opening 45 minutes.
19:20 CET - Bukayo Saka has fired Arsenal into a 32nd-minute lead in Prague, via a well-taken penalty!
Josh Donaldson at Fortuna Arena: For all of Slavia's pressure, Arsenal set-pieces have come to the fore as the Gunners lead 1-0 through Saka's penalty. Corner after corner has peppered the hosts' box, and we awaited another. The referee was called to the screen by VAR to check a potential handball.
It does strike Lukas Provod on the arm, but it's a harsh foul. Arsenal won't care; they have their goal, and they will be confident of keeping their perfect Champions League form intact.
19:15 CET - We've reached the half-hour mark in both Prague and Naples, and we're still waiting for our first goal of the evening...
19:00 CET - An early update from our reporter, Josh Donaldson, at Slavia's Fortuna Arena:
If you thought Slavia Prague were going to roll over to Arsenal in the Czech capital tonight, you are sorely mistaken. Roared on by their fanatical 'tribuna sever', they have been pressing the Gunners all over the pitch, going man-to-man as they try and win the ball back high.
The closest they have come is through Lukas Provod in the opening skirmishes - Arsenal now know they are in a fight.
18:46 CET - We're now underway in both of this evening's early kick-offs. Stay tuned for all the latest updates from Prague and Naples!
18:00 CET - First to the team news for the early matches... Here's the lowdown from our reporter at Slavia Prague's Fortuna Arena, Josh Donaldson:
It's a big night for Slavia Prague, who welcome Arsenal to the Czech capital, looking to cause an upset against one of Europe's in-form teams.
Mikel Arteta revealed on Monday that Viktor Gyokeres didn't travel with the squad, and he is one of four changes to the Gunners' side who beat Burnley 2-0 on Saturday. In the Swede's place comes auxiliary forward Mikel Merino, whilst Ethan Nwaneri, Piero Hincapie and Christian Norgaard all make the starting lineup.
For the hosts, the player to watch is Youssoupha Sanyang. The fast Gambian is making his first Champions League start for Slavia, who will be an unknown quantity to Arsenal.
Below you can see how the teams will line up for Napoli vs Eintracht Frankfurt - still no Kevin De Bruyne or Romelu Lukaku for Antonio Conte's side:
17:45 CET - Hello and welcome to our coverage of the fourth matchday of the UEFA Champions League! We have another blockbuster set of fixtures to enjoy this week, and two absolutely standout fixtures later this evening as Liverpool host Real Madrid and holders PSG take on Bayern Munich.
