Hello and welcome to tonight’s Champions League liveblog.

We’ll mostly be focusing on the action in Group C where it’s Manchester City v Barcelona and Borussia Monchengladbach from 7.45pm.

Arsenal are also in action tonight, having travelled to Bulgaria to face Ludogorets Razgrad.

Team news to follow shortly.

Aguero starts in an attacking City line-up.

Plenty of firepower in the Barca side too….

Here are the line-ups from Borussia Monchengladbach v Celtic:

And finally….Giroud, Ospina and Ramsey start for Arsenal.

For those caught unawares — TV3 is showing Celtic while the Man City are on BT Sport 2.

Just five mins until all of tonight’s games get under way.

Except for the one early kick-off of course, which finished Besiktas 1 Napoli 1 in Group B.

Here is a reminder of how things stand in Group C before tonight’s games:

And they’re off…

Man City pressing Barca very high up the field early on.

Barcelona are keeping the ball well, as per usual.

Celtic, meanwhile, busy in defence already.

It’s been pretty even so far at the Etihad. No chances at either end yet, plenty of passing around midfield.

City, similar to the game at the Nou Camp, look much edgier in possession though.

In Germany, Celtic are struggling to keep the ball for any meaningful spells.

YELLOW for Sterling. Penalty shout for City after some excellent work down the right wing by Aguero.

Sterling made a meal of it but there did seem to be contact. Bit harsh on the England international.

Aguero exposed Barca out wide with his pace, they’ll certainly try that again.

GOALS — Ludogorets are leading Arsenal 2-0 after 16 minutes.

GOAL: Manchester City 0 Barcelona 1 (Messi ’20)

Brilliant from Barcelona. Neymar breaks down the left and Messi finishes off a gorgeous move.

Elsewhere, Arsenal have pulled one back through Granit Xhaka and now trail 2-1 in Bulgaria.

Still no goals in Germany while Barca looks brilliantly dangerous on the counter in Manchester.

OFF THE WOODWORK — Celtic go close top opening the scoring in Germany through Scott Sinclair.

GOAL — Borussia Monchengladbach 1 Celtic 0 (Stindl ’32)

Very bad news for City as the Germans go ahead against Celtic. As things stand City would drop to third in the group with a trip to Germany to come.

Manchester City 1 Barcelona 1 (Gundogan ’39)

Just as Barcelona look like they’re starting to turn the screw. Man City’s press wins the ball back and Gundogan finishes off the move. The Etihad erupts.

Aguero goes close moments later. Game on.

City are playing with their chests out now, taking Barca on.

Elsewhere, Arsenal are back to 2-2 through Giroud. Celtic still trailing 1-0.

Messi goes down in the box under a challenge from Fernandinho. The Argentine looks aggrieved as the ref waves play on and he has a point, Fernandinho didn’t seem to get a lot, if any, of the ball.

HT: Manchester City 1 Barcelona 1, B Monchengladbach 1 Celtic 0

That was an entertaining 45 minutes of football. More of the same of the way in the second half hopefully. We’ll be bringing you through all the action right here.

We’re back under way across Europe.

No changes to either side at the Etihad.

OH DEAR — It opens up for City, Sterling has plenty of space in the box but his touch lets him down and he fires wide. There was nothing wrong with the ball Aguero passed him.

Aguero fires wide just moments later.

Great start to the second half by the home side.

Neymar has hurt his arm after a challenge by Otamendi. He looks OK to continue though.

Silly challenge from Busquets gives City a free-kick just outside the box. Danger here.

GOAL: Manchester City 2 Barcelona 1 (De Bruyne ’51)

Great strike by De Bruyne. He curls it to Ter Stegen’s left and the German can only get a weak hand to it.

Game on at the Etihad.

It’s all Manchester City right now — A De Bruyne free-kick goes right across goal and Otamendi slides agonisingly short of the delivery.

And the trick is almost repeated from the other wing after the resultant corner. Sterling’s delivery this time is a peach but the Argentine defender can’t get on the end of it.

Celtic have started the second half well in Germany and are keeping the ball a bit better.

City v Barca has been a joy to watch, some of the best attacking players in the world showing what they’ve got.

Guardiola’s side much the better side at the moment, and they close again through a Kolarov cross.

OFF THE BAR — Gomes with a stinging shot from the edge of the area after excellent work by Suarez. What a game.

City counter almost immediately and De Bruyne sends an effort from outside the area against the outside of the post. Blink and you’ll miss it.

Jesus Navas is replacing Sterling (71)

Arsenal are still drawing 2-2 in Bulgaria and Celtic trail 1-0 in Germany.

Manchester City 3 Barcelona 1 (Gundogan ’74)

Another great move by City. Aguero, De Bruyne and Navas are involved in the build-up. The Spaniard whips in a wonderful cross after being played in by the Belgian. Aguero can’t turn his delivery home but Gundogan is on hand to tuck the bobbling ball away.

This is turning into a famous night at the Etihad, and one hell of a game.

B Monchengladbach 1 Celtic 1 (Dembele pen, 76)

Dembele tucks it away after he was brought down in the box. The hosts are also reduced to 10 men following the incident as Julian Korb was shown red.

Game on and yet another excellent twist for Man City.

Free-kick for Barcelona in prime Neymar territory. Otamendi clatters into the back of Suarez, who was waiting for the contact.

Messi takes it, even though the free-kick favoured the right footer, but he clips the top of the wall.

Arsenal and Celtic are still drawing their respective games as we enter the final five minutes in the 7.45pm kick-offs.

Ludogorets 2 Arsenal 3 (Ozil 88)

Nolito is on for Kevin De Bruyne at the Etihad

FT: Manchester City 3 Barcelona 1, B Monchengladbach 1 Celtic 1

What a night for Pep Guardiola and Manchester City. Celtic also earned a draw in Germany while Arsenal came from two goals down to win in Bulgaria.

Reports and reaction to follow shortly.
