20:32 | FULL-TIME
After a rather scrappy match, with a combined 12 two-minute suspensions and 12 penalty shots (10 for Celje, including seven scored, and two for Barça) Barça remarkably take a win. They piled pressure on Celje in the last five minutes and two goals by Dika Mem plus a fast break from Aleix Gómez with 14 seconds to go were too much. A couple of fumbled balls and the lead which Celje had held throughout was gone.
Gal Gaberšek was brilliant and his namesake Gal Marguc was top scorer with eight goals. Mem and Hampus Wanne both scored five for Barça, and Emil Nielsen helped secure the win with four saves from eight shots including a crucial one right at the end of the match.
20:20 | FULL-TIME
Despite a nine-goal outing by the impressive centre back Tobias Grøndahl, Elverum concede their 11th defeat of the season and Nantes confirm their place in the play-offs with their seventh win. It's their highest-scoring Champions League win ever, and the match sets a record for both teams when it comes to the combined score of 78 goals. That's largely due to a poor outing by the goalkeepers, who all struggled with the high pace.
20:14 | FULL-TIME
Kielce are in the quarter-finals! Their 10th win of the season gives them 20 points and they cannot now be knocked out of the top two spots in the group.
The Polish side looked strong in the second half, moving out to an early lead against Aalborg and then holding on. Arkadiusz Moryto scored six, with Igor Karacic, Artsem Karalek and Dylan Nahi all adding five goals; Sebastian Barthold also netted six times and Lukas Sandell scored five.
20:10
Nantes' top scorer of the match, Alexandre Cavalcanti, receives a red card for a clumsy foul on Daniel Blomgren which saw Cavalcanti's hand go straight to Blomgren's face. Not that it will make much difference, as Nantes are well clear now.
Celje lead Barça by four goals with just over 10 minutes to play.
20:00
Despite conceding a string of two-minute suspensions - they've had six overall - Celje are still in the lead. Carlos Ortega looks mildly irritated. A loss would make no difference to Barça's fortunes, as they had a three-point buffer ahead of Kielce before this game, but the record champions are not the sort of team to let a game go easily
Kielce are stretching out against Aalborg (28:22), and Nantes maintain their lead against Elverum (34:31).
19:49
Kielce look like they're enjoying themselves now, while Aalborg are into the first timeout of the second half after conceding 10 goals since the restart and scoring just four. It's 25:19 to Kielce and the quarter-finals are beckoning ...
Celje lead Barça by four goals, while Elverum - after a slow beginning to the second half - have pulled back to 25:27 and are putting pressure on Nantes.
19:37
Off we go again for the second halves.
This sort of thing is why Celje are leading Barça.
19:29 | HALF-TIME
A very even first half in every way is level at the break. Both sides have made mistakes, neither is boasting a particularly high scoring percentage, and the top scorers - Arkadiusz Moryto and Lukas Sandell - have both scored four goals. It all sets up an intriguing second half.
Nantes will surely forgive us for saying they had a terrible start to the game; they trailed by five goals halfway through the half, but somehow got themselves back into it and a string of easy strikes towards the end gives them a three-goal lead into the break. Switching out Viktor Hallgrímsson for Manuel Gaspar was key - the Icelandic goalkeeper made no saves in the first 11 minutes, but Gaspar did at least stop some shots once he came on court.
Perhaps the most surprising half-time score is that Celje still lead Barça by three. Two many technical errors and four two-minute suspensions have cost the defending champions and they will need to draw on all their experience to fight back against a very confident host team.
Gal Gaberšek continues to do very well between the posts, but Gonzalo Perez de Vargas has improved as the match has gone on.
19:14
In a flurry of action, Barça's big guns - the likes of Dika Mem and Aleix Gómez - have stepped up and drawn level, although Celje are hanging in there.
There's a similar story in Elverum, where Nantes have closed up from a four-goal deficit to one with Aymeric Minne and Kauldi Odriozola leading the charge.
Jesper Nielsen has just headed to the benches after his shoulder got in the way of Szymon Sicko shooting, but Aalborg lead Kielce by one.
19:05
Celje have had a great start and a quarter of the way into the game still lead Barça by three goals. Gal Gaberšek is the key - while Gonzalo Perez de Vargas is struggling a little, and also missed an empty net attempt on goal.
19:00
Kielce are holding a two-goal lead at 8:6 and Stefan Madsen calls a timeout. He's very intense in his efforts to get Aalborg back on track and it works, as they score two quick goals to get back level.
18:50
We're well underway in all three matches. Remarkably, it took Barça three minutes to find the net as Celje's young goalkeeper Gal Gaberšek saved the first two shots by the defending champions.
Kielce lead Aalborg 4:2, and it's 3:2 to Nantes in Elverum.
18:40
Looks like a good crowd for all three of the early games - coverage has begun on EHFTV.
18:25
There's one later game tonight, with GOG hosting Plock in group A. Victory would see the Danish side safely through to the play-offs; Plock are in seventh, but trail Zagreb by just one point. Perhaps crucially, one of the Polish club's only wins this season was against GOG in round 3 (31:27).
It is GOG left back Nicolai Pedersen's 29th birthday today and you can bet that a win would be a great birthday present.
18:15
The last of today's three early matches is also in group B, and Kielce welcome Aalborg. As we mentioned earlier, one point from this game or the next two will be enough to see Kielce safely through to the quarter-finals, but they need to bounce back from last week's 27:32 defeat in Kiel. Aalborg, meanwhile, ended their series without victories last week in the MOTW against Szeged, winning 33:27.
Aalborg have never beaten Kielce in five previous attempts but lost by just two goals in round 3. They are bringing the same squad to Kielce as the group which beat Szeged last week.
18:05
Another of the early matches today sees Elverum take on Nantes in a snowy Norway. Despite the loss to Celje last week, the French side are still in a comfortable place - third in group B, with 12 points. Second in the group is unlikely as Nantes would have to win all three remaining games while Kielce would have to lose all three.
Elverum are out of contention for the next round, so are playing for pure pride.
17:50
Time for a quick preview of tonight's four games, starting in Celje. Celje had an amazing result last week, beating Nantes in the H Arena 32:31 thanks to their star Aleks Vlah. Vlah is the competition's top scorer to date with 77 goals and will surely add more tonight.
But Barça will be tough opponents. They beat Celje 38:30 in Barcelona in round 3 and have not been beaten in their last 20 Champions League matches; this season, Kiel got closest with a 30:30 draw. If Celje can break that run, they would put themselves in a better position to make the play-offs.
17:00
Kielce are among the teams that could secure their quarter-final spot already in round 12: one point from their last three group matches, starting against Aalborg tonight, will be enough to lock up second place in group B.
They don't get points for it, but the historic visual Kielce have made to celebrate 30 years of EHF Champions League is just amazing! How many players do you recognise?
16:39
While we are going to see plenty of stars taking the courts again today and tomorrow, it is always a joy to look back at the EHF Champions League heroes from the past... like Gudjon Valur Sigurdsson! The Icelandic great features in the latest episode of our This is me series.
"After all, I can only say: thank you handball! You gave me so much. You showed me countries I would have never visited as a tourist, you are the key for so many friendships all over the globe. As a young one, I learnt from the old ones; now it is the opposite. You taught me that you need to fight for every goal, how to cope with setbacks, how to communicate in stress situations, to stand up again."

Here is today's schedule of play for 18:45 and 20:45 CET:
16:00
