Arsenal go hunting for a seventh, but Lucas, who has really been impressive off the bench, can't control the ball in a good position and it goes out for a goal-kick. And that may be that.
90'
NEARLY A SEVENTH! Lucas Perez, tired of playing provider, wants to get in on the act, and nearly makes contact with Ozil's low cross, but it runs out for a goal-kick instead of beating Stoyanov.
87'
M. Özil has scored a goal for Arsenal! Assist by Lucas Pérez.
Decisive cameo off the bench for Lucas!
HAT-TRICK FOR MESUT OZIL! Similar to the fifth goal, but from the opposite flank. Lucas Perez clips in the cross, and the midfielder drifts past his man and volleys it in with his left!
86'
The Arsenal fans are enjoying this display, and are brought into a loud cheer after Koscielny breaks down a dangerous Ludogorets cross into the area, where the visitors had five players waiting.
83'
M. Özil has scored a goal for Arsenal! Assist by Lucas Pérez.
Great run and delivery to match.
ANOTHER FOR OZIL! Lucas Perez storms forward on the counter down the left flank, and plays an excellent cross over the head of two players for the German to slide in on the volley.
81'
Next up for Arsenal is a game against Middlesbrough as they look to usurp Manchester City atop the Premier League table. Both of those teams are level on 19 points after eight games.
80'
J. Lukoki enters the game and replaces Wanderson.
Wanderson exits an on comes Lukoki.
79'
Twenty years into his Arsenal career, will this be the season that Arsene Wenger finally gets his hands on the Champions League? They've been amazing tonight, but with the greatest respect to Ludogorets, it hasn't been the highest calibre opposition.
77'
In the other Group A match, Paris Saint-Germain have gained a 2-0 advantage over Basel. It looks like they and Arsenal will end the night on seven points apiece, well ahead of the other two sides on one point.
74'
Ludogorets have been abject in the second half, and have lost the ball for tue umpteenth time thanks to an uncoordinated attack. They've made it far too easy for Arsenal after Walcott's goal.

Description
73'
A. Iwobi enters the game and replaces A. Sánchez.
Iwobi replaces Alexis, who departs to a warm reception.
72'
Comfortable as you like this game for Arsenal, who saw off a few flurries from the visitors to wrap up the three points here that will keep them top of the group. Wenger will be delighted.
70'
Oxlade-Chamberlain has been hungry all game, and his decision making has steadily improved. He squares up to his man out wide, and gets a cross in that's nearly converted by Lucas Perez.
69'
WHAT A GOAL THAT WOULD HAVE BEEN! Ozil is magnificent, blindly stabbing a ball over the top of the defence for Oxlade-Chamberlain to strike on the volley, but he's denied by Stoyanov!
68'
C. Keșerü enters the game and replaces V. Misidjan.
Misidjan is brought off and on comes Keseru.
66'
Here come Arsenal again. Alexis is onside but he has Palomino for company. The defender does well to stick to the Chilean, and he wins the ball with just enough physical contact to avoid conceding a penalty.
63'
Arsenal try to spark another quick attack as Alexis keeps a hold of the ball and his balance under considerable pressure, before letting it ride for Bellerin, who squares to Gibbs, whose first touch kills the move.
62'
Lucas Pérez enters the game and replaces T. Walcott.
Walcott goes off to a round of applause and on comes Lucas Perez.
61'
Arsenal storm forward once again, but both Walcott and Ozil can't get the ball into the box from either flank. It's now a matter of how many goals the Gunners want from this game.
59'
STOYANOV HAD TO KEEP A HOLD OF THAT! Koscielny plays a great pass forward for Walcott, whose low ball across the face of goal is grabbed just ahead of the waiting Alexis!
57'
Mohamed Elneny enters the game and replaces Santi Cazorla.
That assist is Cazorla's last contribution as Elneny comes on in his place.
56'
M. Özil has scored a goal for Arsenal! Assist by Santi Cazorla.
Lovely searching pass from the Spaniard!
COOL AS YOU LIKE FROM OZIL! Koscielny starts the move with a commanding tackle to break up play. Cazorla picks up the pieces and pings a lovely ball over the top for Ozil, who stays clear of his man and finishes low.
53'
Coquelin really has been superb in this game. He has popped up everywhere in the defensive third to break up play, and his distribution once winning the ball has been spot on.
51'
Cafu makes a move and gets the ball on the left-hand side and is isolated against Mustafi, but he can't advance into a more threatening position and the opportunity dies for Ludogorets.
48'
Is that the three points done and dusted for the Gunners already? It really was the perfect start to the second half for them, as Ludogorets still looked dangerous despite having a two-goal deficit.
46'
A. Oxlade-Chamberlain has scored a goal for Arsenal!
Arsenal score again! Oxlade-Chamberlain spreads the ball wide to Keiran Gibbs, whose low cross is cleared right back into the former Southampton man's path, who smashes it home!
Here we go again.
45' +1
Oxlade-Chamberlain does better this time, advancing down the left and scooping a cross for Alexis to get his head to, but he can't convert at the back post. And with that, the referee blows for half time.
44'
Alexis tucks a pass under his boot and shifts the ball to Oxlade-Chamberlain. He does well initially to beat his first two opponents, but holds onto it for too long, losing possession inside the D.
42'
T. Walcott has scored a goal for Arsenal! Assist by M. Özil.
WALCOTT DOUBLES ARSENAL'S ADVANTAGE! Ozil's cross finds its way to the forward on the edge of the area. An excellent first touch sets him up and it's followed by a lovely, high finish!
Wherever you may be, Ozil will find you.
41'
Poor distribution again from the home side as Oxlade-Chamberlain stabs a throughball that ends up easily at the feet of the defence, before Cazorla lofts a high pass that Stoyanov catches easily.
40'
The first half hasn't gone completely to plan for Arsenal. Yes, they're leading, but they've also wasted chances, and been indebted to Ospina for some quick thinking to deny the spirited side from Bulgaria.
38'
PARRIED! Great hustle from Coquelin to disrupt Ludogorets and win the ball back deep in their half. He sprays a quick pass to put Walcott through, but the forward fires it for the near post instead of across Stoyanov, who makes the stop.
36'
VERY CLOSE FOR LUDOGORETS! Arsenal are caught out by the ball over the top again and Ospina is needed to challenge Misidjan again. The visitors hold onto the ball, but Marcelinho's effort takes a nick off a defender and the post!
34'
Another opening passed Arsenal by as Oxlade-Chamberlain's square ball across the six-yard area is too far ahead of Walcott. Had he made contact, then it would have surely been 2-0.
32'
OSPINA TO THE RESCUE! A perfect ball over the top catches Mustafi out of position, and Misidjan is free on goal, but the keeper is off his line quickly to challenge the wide man for the ball!
30'
Coquelin is the latest player to make inroads into the Ludogorets box via the flanks, but his low cross is easy for Stoyanov to take care of. Good spell this from Arsenal, who will want a second goal.
28'
CHANCE FOR OZIL! Walcott is away down the right and plays a low ball into the area that's cleared into the path of the German inside the box, but he takes too long to apply the finish and it's blocked.
26'
Alexis really loves that knuckle-ball chip over the top of the defence, and he tries to find Walcott with just such a ball, but it doesn't quite work out for Arsenal as Ludogorets escape.
24'
The left side of Arsenal's defence is looking like a weak point that Ludogorets are trying to prise open. Cafu gets free on that side again, rounding Ospina but running out of room in the end.
22'
Alexis gets the ball and charges into the Ludogorets half, heading for the left flank before he's brought down. It's a free-kick for the hosts, but Ozil's delivery is too strong and punched clear by Stoyanov.
20'
Ludogorets haven't been terrible on the ball by any means, and there's signs that they can cause this Arsenal defence more problems, especially when the full-backs get sucked up too far.
18'
BEATEN AWAY BY OSPINA! Ludogorets just remind Arsenal that they're not here to make up the numbers as Misidjan ghosts through a gap between Gibbs and Koscielny, but he was denied by the Colombian stopper.
16'
That's two passes in as many minutes that Arsenal have flubbed that could have put someone through behind the defence. First Ozil then Bellerin fail to find their range from good positions.
14'
Well you can't say that it hasn't been coming. Arsenal have been in the ascendancy since the first whistle and have created chances. They look dangerous whenever they break, and more goals could follow if they keep it up.
12'
A. Sánchez has scored a goal for Arsenal! Assist by A. Oxlade-Chamberlain.
MAGNIFICENT FINISH FROM ALEXIS! The Chilean is put through down the left again and once more, he cuts back, but this time, he makes no mistake. He chips a delicious effort over the keeper and into the far corner!
Good ball behind the defence from the Ox.
11'
ANOTHER OPENING! Ozil times a perfect pass for Alexis, who is clear behind the defence, but he doesn't get quite up to full speed, which allows men to get back and put him off his finish.
9'
WALCOTT SHOULD SCORE! Alexis does excellently to double back from a long ball and spread it to the England man. Pimienta's attempt at a block doesn't do enough, but instead of finishing at the back post, he tries to square it for a team-mate and it's cleared.
7'
Bellerin turns on the afterburners to stream past his man, and he pings a low cross into the area, but Alexis can't get on the end of it. Arsenal are starting to apply more pressure here.
5'
Koscielny passes to Ozil, who takes it seamlessly on the turn and tries to angle it towards the far post for the arriving Alexis, but he puts it right into the path of Stoyanov, who keeps a steady hold of it.
3'
Some good early possession for Ludogorets on the left-hand side, as Wanderson spreads it wide to Cafu, but the striker's cut-back into the area is intercepted by Coquelin, who had dropped back.
1'
Off we go!
For the third Champions League group stage game in a row, Georgi Dermendzhiev sticks with the same starting 11. A lot will depend on playmaker Marcelinho, and striker Jonathan Cafu, with the pair combining to score the goal that earned Ludogorets their only point of the group stages against Basel.
Arsene Wenger rotates his squad, giving the likes of David Ospina, Alex Oxlade-Chamberlain, Francis Coquelin and Keiran Gibbs some game time. Alexis Sanchez, Mesut Ozil and Theo Walcott continue in attack.
Ludogorets drew with Basel, which marks the only point for either side in the group stages so far. They're currently second in the Bulgarian first league, two points behind leaders Levski Sofia, but with a game in hand.
Arsenal beat Basel and drew with PSG to pick up four points and the Group A lead from their opening two games. They will fancy their chances against the Bulgarians, with a win here tonight leaving them in a great position to qualify.
Hello and welcome to our live commentary of the Champions League meeting between Arsenal and Ludogorets at the Emirates. The in-form hosts welcome a side that are yet to win in Group A in the first of two back-to-back meetings.
So far, so good for Arsenal in what has been a chance-heavy game for both sides. Ultimately, the Gunners have been more clinical when it's counted, taking a two-goal lead thanks to splendid efforts from Alexis and Walcott. Ludogorets have given a good account of themselves, but have a lot of work to do in the second half.
Seven wins from seven now for Arsenal, who are in a lovely run of form. They outclassed Ludogorets tonight, thanks to Mesut Ozil's first-ever professional hat-trick. Seven points from three games for the Gunners, and they're on course to reach the last 16. That's all from us, thanks for tuning in!
