It's all over. A magnificent performance from Arsenal, albeit against opposition who rarely threatened.
Nketiah breaks at pace and Giroud receives the ball on the right. His shot is blocked.
Volodko has a fierce shot from outside the area, which Ospina blocks!
BATE break with numbers! It's three-on-three, but Volodko chooses to launch an innaccurate longshot.
BATE have had a little more possession as play winds down in the final few minutes. Rios puts in a speculative cross but no one is there for it.
Berezkin launches a curling effort from outside the area which goes narrowly wide. Ospina was scrambling to reach it.
Nketiah beats his man on the left and charges into the area before being dispossessed. He's a firm fan favourite and receives rapturous cheers.
Hit for six.
Wilshere runs sinto an excellent position between the BATE defenders and is unselfish in distributing to Nelson on the right. Nelson's shot is deflected. If Wilshere had kept it himself he would have had a clear shot on goal.
DOUBLE SUB: Welbeck and Elneny are replaced by Nketiah and Willock.
SUB: BATE use their final change to replace Ivanic with Yablonski.
Wilshere has been the star of the show tonight. Albeit, a star who has often been afforded all the space and time he needs.
It's a beauty from Elneny! Wilshere receives the ball at the top of the box, looks up and passes to the Egyptian on the left side of the area. He hits a wonderful first-time left-footed curled shot past the 'keeper.
Ospina needs to come to the edge of the area to prevent Signevich from latching onto a long ball.
Wilshere, in acres of space in the middle again, feeds Nelson on the right, but Milunović intercepts well.
SUB: Walcott is replaced by Reiss Nelson.
CHANCE: Ivanic finds Gordeychuk with a deep cross, which is hit into the side netting. BATE has string together a few good chances in the past few minutes.
SUB: After his bright moment, Stasevich is immediately replaced by Finnish midfielder Jasse Tuominen
Stasevich collects a cross on the edge of the area, turns and shoots at Ospina! It's a beautiful-looking attempt at goal, but not fruitful.
Gordeychuk has a faorly decent first-time shot on the edge of the area blocked by CHambers. It might be BATE's best chance of the game.
BATE try to break forward and Dragun takes a poke from distance. It goes nowhere near the goal.
The first penalty was ruled out for encroachment.
GOAL! Giroud converts the penalty on the second time of asking, although the 'keeper got a hand to it.
Giroud converts the penalty but the ref makes him take it again!
PENALTY! Walcott goes down under a challange from Milunović and the ref blows up.
Rob Holding makes a diving clearance as BATE put in a rare cross.
Walcott advances down the middle and feeds Giroud on the right. The Frenchman composes himself and then blasts a shot high and wide.
Wilshere has acres of space around 35 yards from goal. He finds Welbeck on the left near the touchline, but his cross is disappointing.
Welbeck charges down the right flank and cuts onto his left foot, Robben-style, but his shot is blocked.
SUB: Signevich replaces Rodionov. That's an attacker for an attacker.
Giroud steals possession around 35 yards from goal. He charges forward and shoots from outside the box but it's deflected for a corner.
BATE attack with Rios on the right, but Arsenal diffuse the danger on the edge of their area.
Welbeck was lurking just behind Polyakov so he had to act, but he won't want to see that again.
It's a terrible goal for Polyakov. Wilshere splits the defence with a wonderful pass to Walcott on the right. His cross finds Polyakov, whose clearance ends up in the net.
There is a fan wearing an Arsenal-BATE half-and-half scarf in the sparse crowd. His neighbour appears to be filming the action on a large iPad.
BATE force a corner, which Milunović heads comfortably into Ospina's arms. It might be the first thing he's had to do tonight.
There's no changes to report at the interval, but we should expect some Arsenal youngsters to be introduced in this period.
We're off! BATE batten down the hatches for another 45-minute assault.
The first half ends and Wenger can have no complaints about that. BATE have absolutely no answers for Arsenal's quality tonight.
Wilshere has been very good tonight. He's dictating almost all the play on the edge of BATE's area.
Wilshere gets the goal he deserves! Walcott finds Wilshere on the edge of the area, he takes one touch and blasts a powerful shot from 15 yards!
Wilshere has time and space on the edge of the area. The crowd scream "SHOOT!" and he obliges. His left-footed effort is tipped over for a corner.
CHANCE: Maitland-Niles finds WIlshere on the right side of the box and he lets the ball roll to Walcott. His low shot is blocked by Milunović.
It was Coquelin who found Welbeck on the edge of the area in the build-up to the goal. The pass was brilliant.
That goal was a long time coming. Arsenal must be commended with the speed with which they advanced in the final third.
Danny Welbeck beats a defender in the box and Polyakov intercepts, only for the ball to fall to Walcott. He has plenty of space to slot in the second!
According to UEFA, Arsenal have completed 258 passes and have had 72% possession.
BATE make a rare advance upfield but Gordeychuk is flagged offside.
Coquelin is on the floor after an aerial challenge in the middle of the field. He gets up clutching his lower back.
Maitland-Niles tries to find a free Walcott on the right side of the box but he puts too much on the pass. BATE are not in this at all right now.
Arsenal are hammering the BATE box at the moment. Wilshere goes down in the area after taking a swipe in the face from Milunović on the edge of the area. The ref doesn't see it.
Arsenal win a free kick just left-of-centre, 20 yards out. Walcott strikes it low, just past the 'keeper's left-hand post.
There's some lovely PlayStation-esque movement going on among Arsenal's front line tonight.
CHANCE: Wilshere chips another ball onto Giroud's head. He puts it in the path of an advancing Walcott, who sees his shot tipped out for a corner!
CHANCE: Wilshere delivers a lovely ball over the top and Giroud's header is tipped away by Scherbitski! Corner!
A snapshot of the crowd tonight...
Goalkeeper Scherbitski makes a bizarre decision to come out of his box to take the ball off Welbeck on the left, despite the fact that Giroud is waiting in the middle. The 'keeper only just gets away with it by pulling off the clearance. That could have been embarrassing.
Debuchy's goal was Arsenal's 100th of 2017.
Arsenal have had 70% possession so far.
Maitland-Niles picks out Welbeck's run into the box with a superb pass and Welbeck goes down. He believes there is contact, but the referee isn't buying it.
Volodko is a dead ringer for Andriy Voronin - particularly in BATE's Ukraine-style yellow and blue away kit.
Volodko sees yellow for a fairly nasty challenge on Debuchy near the half-way line.
Walcott's corner is intended for Giroud, but it's cleared.
Wilshere feeds Maitland-Niles on the left, whose cross is blocked for another corner.
The camera cuts to Arsenal's bench, which looks like a GCSE field trip. A lot of youth there.
Elneny delivers a wonderful cross into the box for Giroud, but it's cleared for a corner.
That's Debuchy's first goal since December 2014.
Debuchy did well to make such a sweet connection for the goal, but also to play on after what seemed a clear foul on Walcott in the box.
Walcott goes down in the box and has a strong penalty claim, but the ref plays advantage as Debuchy strikes the ball from the right-corner of the area. It's an absolutely magnificent hit!
Arsenal are in the swing now. Coquelin wins a throw-in near the corner flag after another attack down the right flank.
Walcott takes a shot from just outside the box and it smashes defender Milunović right in the face. It looks painful and the ref stops play.
Wilshere tries to find Walcott in the box, but the latter is called offside.
Ivanić's chance came after Welbeck gave up a free kick in his own half for a foul on Dragun.
CHANCE: Ivanić wins the ball on the edge of the area and has the space to get a shot off... but it ends up in Row Z.
Chambers has the opportunity to set Debuchy free on the right, but his aerial pass goes out of play.
Gordeychuk chases down a ball on the right flank but it goes out for a goal kick. It's a low key start to the game, the home side have not settled yet.
CHANCE: Debuchy flicks a ball in from the right and Walcott and Girous both get their head on it before Elneny takes a shot. He hits the post! A great opportunity to open the scoring.
There are an awful lot of empty seats at the Emirates. The pitch, as always, looks immaculate.
Gordeychuk charges down the right and tries to find Dragun, but the cross is blocked. Early danger from BATE.
We're off! Austrian ref Robert Schörgenhofer blows his whistle and BATE take the first touch.
BATE have only won two of their last 20 European away games.
BATE's record in the 2017-18 competition so far: W1 D2 L2. Their victory was a 1-0 home win over Cologne on matchday three.
We are around three weeks away from a very important milestone: the one-year anniversary of BATE's last English-language tweet...
Tonight marks Giroud's 40th European outing. He has 16 goals in UEFA competitions.
Kick-off is five minutes away. A reminder of the permutations: Arsenal will finish top of the group regardless of tonight's outcome. BATE may only progress if they win in London and Red Star Belgrade hold Cologne to a draw.
Arsenal are undefeated in their last seven European group stage games at home. Their aggregate score in those games is 18-3.
BATE have won the last 11 (ELEVEN) Belarusian Premier League titles. The season finished two weeks ago and won't start again until April.
They last featured in the Champions League in 2015-16, but have never cleared the group stage in any European competition.
On Europa League matchday two, Arsenal won 4-2 at the Borisov Arena, with goals from Rob Holding, Olivier Giroud and a brace from Theo Walcott.
Eighteen-year-old forward Eddie Nketiah, who played with Chelsea's youth academy until 2015, signed a new long-term contract with the Gunners yesterday. You may remember him from his sensational first-touch goal in the EFL Cup win over Norwich last month. He earns a spot on the bench tonight.
In the interest of high-squad-number balanced reporting, Nketiah also wears 62.
BATE attacking midfielder Mikhail Gordeichuk will be wearing the number 62 tonight. If Georgian midfielder Valerian Gvilia comes off the bench, he will be wearing 80.
Down with this sort of thing.
BATE haven't played since they won the Belarusian Premier League on November 26th. They squeaked it with a thrilling 3-3 draw at Gorodeya on the final day, allowing them to finish above Dinamo Minsk on goal difference.
It's possible they won;t be quite as fresh as the Gunners.
Wilshere starts tonight, despite his terrifying foray into ice skating with his small child earlier this week.
Wenger: "You can do ice skating by bringing your child on and just making sure nothing happens to him, or [you can do] ice skating violently. I don't think he did that."
Arsenal have made a full eleven changes from the side that lost 3-1 to Manchester United last weekend. However, this may be testament to the strength of Wenger's squad: Giroud will play in front of a trio of England internationals in Welbeck, Wilshere and Walcott.
Forget MSN and BBC - Arsenal have WWW. Or, 'The Internet' as I shall now be calling them.
ARSENAL: Ospina, Debuchy, Chambers, Holding, Maitland-Niles, Elneny, Coquelin, Wilshere, Walcott, Welbeck, Giroud. Subs: Macey, Sheaf, Nelson, Reine-Adelaide, Willock, Nketiah, Akpom /// BATE BORISOV: Scherbitski, Berezkin, Ivanić, Rios, Milunović, Rodionov, Dragun, Stasevich, Polyakov, Volodko, Gordeichuk. Subs: Chichkan, Yablonski, Buljat, Signevich, Tyominen, Baga, Gvilia
We wait with BATED breath for the BATE team. In the meantime, it's interesting to see Maitland-Niles in the left-back position, while it may also be regarded as curious to start two defensive midfielders in a low-stakes game against a Belarusian side.
Arsene Wenger promised "quite an experienced team" tonight, but much of that experience has been of testing the seats in the dugout.
Walcott, Welbeck and Giroud front the Gunners' 4-3-3, while there's a rare start for Maitland-Niles in the back.
While we await the team news, a reminder of what's at stake in this final group game: Arsenal are already guaranteed top spot in Group H, BATE can only qualify if they win and the match between Red Star Belgrade and Cologne is a draw.
