Evening all, and a poser to begin: are Arsenal a)no longer Arsenal; or b) still the same old Arsenal?

So thanks for your company - enjoy the rest of your night.

Brilliant win for Arsenal, and a brilliant winning goal. They didn't play that well, but they found a way, and that's just as important. They're not going to win this competition, but the momentum will be very useful in continuing their charge in the league.

Full-time: Ludogorets 2-3 Arsenal

Ludogorets press, and Oxlade-Chamberlain clumps behind for a corner. Wanderson with it, and for a second the ball is loose in the box when Koscielny is beaten to the header, but Coquelin is there to smack clear.

Get a load of this.

There will be three added minutes.

This is a huge night for Arsenal. They've come back from a deficit, played badly thereafter, and found the moment of genius that they needed and the moment that they needed it.

WHAT A GOAL! LUDOGORETS 2-3 ARSENAL (OZIL) This is the definition of class and composure. A long hump finds Ozil and the keeper charges out, so Ozil lifts the bouncing ball over him, then as two defenders cover the line, he feints to shoot, they slide in to block, look silly, and he mooches across the face then slots into the empty net. Outstanding behaviour.

This has been a really disappointing effort form Arsenal. Having done so well to get back into the game, a fierce start to the second half would have seriously discouraged Ludogorets. But they were reactive, and haven't been able to rouse themselves.

Ozil appears at inside-left and he crosses for Oxlade-Chamberlain at the near post, who tries to let the ball run across his instep and ino the far corner, but gets the timing wrong, so it zoots wide.

Wanderson is allowed to carry the ball from the left touchline the middle of the pitch, feeding Misidjan who crosses into Ospina's arms.

Arsenal give away consecutive fouls as Ludogorets attack their left-hand side. Nothing comes of them, but the home crowd sense that their side is in the ascendancy and roar them forward.

Goal news from elsewhere: Basel have equalised against PSG, which would unqualify both PSG and Arsenal; Manchester City now lead Barcelona 3-1, and have apparently handed them a lesson in the second half.

Keseru's night is over; he's replaced by Misidjan.

I'm not sure this means very much, but in case.

Ludogorets have experienced all manner of emotional swing during this game, and they're visibly growing in confidence now - they've largely frustrated Arsenal since half-time, creating the two best chances for themselves. It means nothing, but they look the likeliest winners.

Aaron Ramsey, who's been ineffective in the second half but had a good run-out, is replaced by Alex Oxlade-Chamberlain.

Piqued, Sanchez powers past Marcelinho to get at Anicet, snapping into him but avoiding a card.

First bit of Arsenal in a while, Xhaka firing a pass at Sanchez who has to touch it into his stride to put himself in on goal. But he can't quite manage it, Borjan able to smother as he chases after it.

It's not much of game anymore, but Marcelinho breaks forward at inside-left and slides a pass for Keseru ahead of him, but without the angle to allow him to drive towards goal.
