Evening all, and let's have some Arsenal-PFC Ludogorets Razgrad.

Well, that wasn't quite as simple as the scoreline suggests - Ludogorets caused Arsenal plenty of problems in the first half. But Arsenal finished superbly and are playing with confidence and conviction. The question, as ever, is whether they can keep it going when things get serious.

There shall be two additional minutes.

GOAL! HAT-TRICK! ARSENAL 6-0 LUDOGORETS (OZIL) Well, he's not even played that well, but he's finished with an absolute absence of ruth. Perez goes down the right this time, comes back in on his left side, clips over a cross, and Ozil arrives to toe-lace a volley into the near post corner.

It's been a good night for Oxlade-Chamberlain. He's not played well enough to teef Iwobi's spot in the side, but he's in the conversation.

How crucial was that last-minute winner at Burnley.

GOAL! ARSENAL 5-0 LUDOGORETS (OZIL) Perez makes a run in behind, down the left, and Oxlade-Chamberlain finds him. There is only one defender in the box, but the clipped cross is still a goodun, directly into the path of Ozil, who cushions a finish into the ground and over the keeper.

Ludogorets are keeping possession, hoping to avoid further damage and expenditure of energy.

Change for Ludogorets: Lukoki replaces Wanderson.

Marcelinho finds some space on the left and finds Anicet outside the box; he makes room for a shot, and cracks it wide. That's the first such incident in quite some time.

Gladbach now lead Celtic 2-0. It's not been a good night for Manchester City.

Ludogorets have barely been out of their own half this half.

Alexis Sanchez looks as unhappy with his subbing as you'd expect . He is a footballing monster.

In Barcelona, Lee-Nell Messi has a hat-trick.

Alexis Sanchez departs to a standing ovation, and he really has earned the arse out of it. Alex Iwobi replaces him.

Oh this is lovely, Ozil snapping a pass from out on the left into the feet off Sanchez. He looks right and scoops left, picking out Oxlade-Chamberlain, inside the box, who watches the ball onto his laces but can only smack it into the ground, the save an easy one for Stoyanov. But still, that was the football of a player and team whose needle is well and truly hitting the groove.

Ludogorets haven't been able to get close to Sanchez tonight, and again he pulls away through the middle. But Palomino goes with him, bundling him to the ground but making it look like a tangle of bodies, and the ref says no penalty.

I reckon Ludogorets would take 6-0 if you offered it them.

Oh this is lovely, Oxlade-Chamberlain down the left and teasing Minev before knocking a pass back to Ozil. Somehow, he kind of runs into it without breaking stride, sending an entirely unexpected return back - but Oxlade-Chamberlain can't quite control it.
