As the pace picked up in the second half and the mistakes crept in, it proved more costly for Kiel - despite a very good Niklas Landin. Kiel travel to Paris next week with four goals to try and make up. In recent times they have never beaten PSG by that much at home.
Sander Sagosen showed he is back on form with nine goals (from 15 shots). For PSG, Dainis Kristopans, Ferran Sole and Elohim Prandi all scored six.
22:22
And now a third suspension and a red card for Hendrik Pekeler for pushing Luc Steins. PSG lead 30:27 and there's just over a minute to go.
22:19
It hasn't quite gone to the script for Kiel since this moment, but this is a good save.
22:16
Dainis Kristopans receives his third suspension in the game and is off. He basically ran straight into Niklas Landin after a particularly aggressive shot. The big Latvian has put in a shift though, scoring six goals from six shots and adding two assists and a block; if PSG hold on for the win it's thanks in no small part to Kristopans.
22:10
PSG have regained the lead and extended it to three goals. They haven't beaten Kiel at home since September 2017, back in that season's group phase. Several Paris players, including Elohim Prandi, are really on form.
22:00
Approaching 14 minutes, and with Dainis Kristopans suspended for a foul on Domagoj Duvnjak, a Dominik Mathé shot is saved and Rune Dahmke picks up the rebound and scores into the empty PSG net. It's a level game! The crowd go suitably wild, and Raul Gonzalez calls a timeout.
21:55
Filip Jicha uses another timeout. PSG remain just in control, with a 19:16 lead, but there's loads of time for Kiel to catch up if they increase the efficiency of their attack and get past Jannick Green. Niklas Landin is starting to really up his game now too.
21:48
Six minutes into the half and Kiel have not scored a single goal. Everything has been blocked, saved or simply missed. The home team are back into a seven-on-six attack.
21:42
Kiel had a good start to the half, with Niklas Landin making an outrageously good save of a Luc Steins shot - but two PSG goals then extend the visitors' lead to 15:12. And Patrick Wiencek is suspended for fouling Elohim Prandi.
Time for Kiel to really dig in and step up in attack.
21:35
Petar Nenadic seems to be fitting pretty well into the PSG squad after his transfer from Veszprém - here's his first Champions League goal for his new team.
21:26 | HALF-TIME
A Dainis Kristopans goal is swiftly followed by a Magnus Landin goal as the pace picks up just before the end of the half. Raul Gonzalez uses a timeout with 15 seconds to go and Kamil Syprzak scores; Filip Jicha follows suit to try and equalise before the buzzer - but Jannick Green saves Sander Sagosen's shot.
So far the two goalkeepers have been dictating the pace. Green has made seven saves (38.9 per cent) and Niklas Landin six (33.3 per cent). Sagosen is top scorer with four goals, but that's only half of his attempts. Kristopans, with three from three, is looking dangerous - will Kiel try and stop him in the second half?
21:13
So why are PSG leading Kiel by only nine goals to eight after 24 minutes? Well, because of Jannick Green and Niklas Landin, who are both stopping an incredible number of goals.
21:05
After one low-scoring match we have another on our hands - 18 minutes in, it's 7:7 after Niclas Ekberg nets a penalty for Kiel.
20:55
The importance of Niklas Landin to Kiel is well-known, but so far it's PSG goalkeeper Jannick Green who's having a better day. He's made three saves in a row, stopping Patrick Wiencek, Sander Sagosen and Miha Zarabec.
It's 3:3 and Landin slowly starts to find his form, catching the last shot by Elohim Prandi and stepping off as Kiel go seven-on-six.
20:47
Thirty seconds in and Kiel get on the scoreboard thanks to Miha Zarabec; just over a minute later Zarabec scores again and the hosts have a 2:0 lead.
20:40

This clever penalty by Tin Lucin sparked Plock's comeback. It wasn't Lucin's best game, but he proved his worth here.
20:26 | FULL-TIME
That's the lowest combined score for both Plock and Magdeburg this season, and they both matched their lowest individual scores too. Plock found something in the closing minutes and were able to equalise - although Magdeburg then took a timeout the resulting attack was scrappy and Michael Damgaard's long-range shot happened after he landed. Bennet Wiegert was unhappy, earned himself a two-minute suspension, and gave Plock an opportunity to win.
But Sergei Kosorotov's last shot was stopped by Mike Jensen, who has been extremely good, and that's it. Somehow Plock have come out of the game level, despite trailing by four or five goals for much of the match.
20:15
Michael Damgaard has led the way for Magdeburg in one of his most impactful games this season, with five goals including this one.
20:10
We've had a couple of timeouts. In Magdeburg's, there were lots of instructions from Bennet Wiegert for Kay Smits. Now Xavi Sabate takes a timeout. He's very calm and doesn't take up too much time, showing his players the moves he wants them to make and sending them off to do it. But the attack fails, because it's that sort of game, and Plock are back defending another Magdeburg possession.
20:02
A couple of turnovers and more success in defence, and suddenly it's a two-goal game - Magdeburg lead 18:16.
19:57
Owch ... Lucas Meister shoots rather blindly and the ball ricochets off Ignacio Biosca's head. He heads off court for a sit-down and Marcel Jastrzebski comes on, but only briefly as Biosca is soon back on court. It's 13:17.
19:51
Xavi Sabate gestures fiercely; Plock are now trailing 12:16, but at least are scoring, and have stepped up their defence.
19:45
The first five minutes back are all going Magdeburg's way - they've scored twice, and Plock have had no success.
19:38

19:35
Before the second half gets going, check out this excellent Ignacio Biosca save. He needs a few more along the same lines if Plock want to stay close to Magdeburg ahead of the second leg.
19:27 | HALF-TIME
This is a nervy, slow-paced game. Magdeburg are moving better than Plock, who seem content to largely pass the ball when in possession. The home side have bounced back a bit from their poor start, but Magdeburg are still more effective in attack and defence. Michael Damgaard is making his presence felt with a couple of good goals, as is Piotr Chrapkowski who gets a few slaps on the back from his teammates for his defensive work in the first half.
The goal timeline tells a tale of the way the game has unfolded so far.
19:16
We now have a clip of Philipp Weber's insane goal earlier on.
Plock are really back in this, closing up to 8:9 and with Ignacio Biosca getting into his stride.
19:10
Niko Mindegia's goal has given Plock a new drive and suddenly they're back to 5:7, playing seven-on-six - which backfires when the ball is turned over and passed to Kay Smits to score into the empty net.
Here's some early Mike Jensen saves too to enjoy.
19:05
Magdeburg are not giving Plock many chances and move out to a 7:2 lead before Niko Mindegia scores their first goal in 10 minutes.
18:57
Philipp Weber scores a bonkers goal, shooting and rolling at the same time, and Magdeburg go 5:2 up. Their defence is keeping Plock out and Xavi Sabate calls a timeout.
"The difference is shooting, but don't shoot fast," says Sabate, reminding his team it's still early days and they can find a solution.
18:50
Just under three minutes in and Magdeburg have a 2:1 lead. The fans are on their feet - what an atmosphere!

Speaking of Kiel vs PSG, Paris have made a great hype video - give it a watch.
18:05
The second match on today at 20:45 CEST is a classic - Kiel vs Paris Saint-Germain. They're familiar foes, meeting in the quarter-finals for the third year running.
To make the game more important, it's Kiel's 100th anniversary this year. And in their 25th appearance in the EHF Champions League, and with key players including Sander Sagosen leaving at the end of the season, they will not want to go out with a quarter-final loss. EHF journalist Björn Pazen has looked at Kiel's history ahead of today's game.
