Right then, with Sam Allardyce stubbornly refusing to talk to TV people, or TV people stubbornly refusing to broadcast it, I’m going to slope off. Here’s the match report again. Bye!

Mikel Arteta is well chuffed:

A very convincing win, to win the last three games in the Premier League is not easy. Today, when conditions were better, we played some great football. I think the first two goals, the first with Tierney was terrific, the second, the combination play was fantastic as well, and the clean sheet, it gives us the platform to go and win the games. I’m so happy we were able to achieve the target that we had [to win their three festive fixtures] because the table looks completely different, the energy around the place is much better, and wins bring confidence. We’ve got a week now to prepare for another competition, so enjoy tonight, enjoy the victory, go back home if the weather allows and be ready for the next one.

Kieran Tierney has a quick chat. Of his goal, he says “the boys are calling it a cross”. Also:

We wanted to build up points, climb up the table, and the last few games we’ve done that. It’s just consistent hard work. We’ve not changed anything. It’s coming together now. It’s progression. We’re not going to win every game until the end of the season, it’s about building points, getting up the table, catching the team in front of you. The next game’s always the most important one.

Paul Doyle has filed his match report from the Hawthorns:

Fairweather footballers? Not Arsenal, at least not here. Mikel Arteta’s team made light of fierce conditions and desperate opponents to produce possibly their best performance of the season. Kieran Tierney, Bukayo Saka and Alexandre Lacazette scored beautiful goals and, along with 20-year-old Emile Smith Rowe, delivered outstanding displays, helping to give Arsenal a third consecutive victory and renewed hope of a bright future. For West Brom the forecast is bleak.

Much more here:

Tonight the English Premier League table looks like this:

90+4 mins: It’s all over, and Arsenal have won this game of football at a canter.

90+3 mins: Another shot on target for West Brom! Pereira’s square pass from the right finds Harper, whose low left-footer from 20 yards or so is tipped wide by Leno.

90+2 mins: Willian cuts in from the right, past O’Shea, past Gallagher, and shoots at Johnstone from the edge of the area.

90+1 mins: There will be three minutes of bonus time.

89 mins: West Brom have their second shot on target, and their first in well over an hour. It’s Gallagher’s effort, from 30 yards, which is firmly struck but straight at Leno.

87 mins: Ceballos slides in on Robinson, wins the ball, takes the man and gets a booking.

86 mins: Arsenal are passing the ball around for the love of passing. They have had 82% of possession in the last five minutes, BT Sport says.

82 mins: And nearly another! Willian feeds Lacazette, who runs into the right side of the penalty area before sliding the ball across goal, but Aubameyang can’t get a toe to it to turn it in!

82 mins: West Brom bring Rakeem Harper on for Phillips.

80 mins: Willian gives the ball away just outside his own penalty area but West Brom can’t capitalise, and instead they nearly go five down within 20 seconds. Arsenal clear and Aubameyang runs into the area and past Bartley before lashing a shot goalwards which Johnstone beats away.

79 mins: West Brom have a shot! A cross from the left finds three of the home side’s players at the far post competing for the chance to have a go. Austin wins the battle, and half-volleys well wide.

77 mins: Joe Willock comes on for Emile Smith Rowe, who was at the heart of Arsenal’s best moves during the part of the game when Arsenal were full of great moves.

75 mins: Arsenal hog the ball for a while, the move ending with Tierney’s cross dropping to Willian, who should score but volleys instead at Aubameyang, who could turn it in but instead deflects it over!

73 mins: It seems to have stopped snowing snow. It might not have stopped raining goals.

72 mins: Arsenal lead 16-3 on shots, 10-1 on shots on target. “Sam Allardyce’s head looks like a Toby jug which has realised that it’s been used as a chamberpot,” writes Charles Antaki.

70 mins: Saka is fine, but he’s coming off anyway, and Willian is coming on instead.

70 mins: Gallagher is booked for tripping Saka.

70 mins: Arsenal just had to defend a bit.

66 mins: West Brom bring Kyle Bartley on, and take off Ivanovic.

Aubameyang cuts infield, drags a couple of defenders with him and then passes wide to Tierney, all on his own on the left, who crosses to Lacazette, all on his own six yards from goal, who taps in!

63 mins: And now it’s all Arsenal again.

And there is another goal - but it goes to Arsenal! Ajayi miscontrols and Arsenal move the ball to the right, where Saka crosses. Here Ajayi intervenes again, to volley the ball against his own post. It rebounds to Smith-Rowe, whose shot rebounds to Lacazette, who turns it in! That is an absolute nightmare of a goal for Semi Ajayi.

59 mins: Arsenal are also playing with reduced intensity, which is helping the home side’s low-level improvement. Also, Aubameyang has been remarkably peripheral throughout. One goal and it’s all to play for.

55 mins: Lacazette is played in, pushes the ball past the keeper on the right of goal, but is left with an unhelpfully acute angle, his shot has the pace removed by a deflection off Johnstone, and O’Shea clears.

54 mins: Bellerin has been taken off, and Maitland-Niles has come on.

53 mins: West Brom are doing much better in the early stages of this half. Which is to say, not completely terribly. They’ve tried a couple of crosses already, which is quite the improvement.

51 mins: Arsenal cut through West Brom again, but Bellerin’s cross is too close to Johnstone, who catches. The ball is starting to hold up a bit in the snow in some places, so perhaps the home side are tactically not running, to encourage further snow buildup.

50 mins: “Could it be possible for the match be snowed off, if the penalty area line is no longer visible?” asks Jukka Itäkylä. In theory perhaps, but the lines and the penalty areas have had a damned good brushing at half-time and look pretty clear for now.

47 mins: West Brom have the ball in the net, but the flag is up! The ball is lifted over the defence to Pereira, clean through to the left of goal. He shot deflects off Leno onto the far post, rebounds to the edge of the area, and Robinson lashes in the loose ball! Celebrations are cut short by the linesman’s flag, Pereira having been about three yards offside at the start of the attack.

46 mins: Peeeeeep! Action has resumed.

The teams are back out, and West Brom have brought Charlie Austin on for Grady Diangana.

Sure, three goals isn’t very many, but it’s more than anyone else.

Before today, Arsenal had the third-worst record in the Premier League in the first half of matches, ahead of just Sheffield United and (by a point) West Brom (they will now rise a little to 16th). In second halves they are seventh, and West Brom 18th.

45+2 mins: And that’s it! Two excellent goals and a general feeling of supremacy for Arsenal, 15 minutes to pray for further blizzards and perhaps a floodlight failure for West Brom.

45+1 mins: There will be two minutes of further misery stoppage time before West Brom can warm their bodies and lick their wounds.

44 mins: Tierney finds Lacazette running down the left, and he cuts inside Ivanovic with insulting ease and is clear on goal, albeit from an unpromising angle. He shoots anyway, and it bounces clear off Johnstone.

41 mins: Bellerin fouls Gallagher, and is awarded the night’s first caution.

40 mins: West Brom win a corner, and Ajayi wins the header, but the ball goes well wide. Still, it’s a shot (Arsenal just 10-2 ahead on shots now).

39 mins: The second goal in full. Really top class.

38 mins: The snow has calmed a bit, and the ball leaves a cleared trail as it rolls along the ground, like some kind of synthetic snail.

36 mins: O’Shea tries a long throw, but the ball slips from his hands and loops to the nearest defender.

34 mins: “Would Tierney’s wonder goal count on his record if the match is abandoned,” asks Gary Naylor. “60 years ago, Denis Law scored a double hat-trick that was chalked off.” I once talked to him about that match, a cup game against Luton, but strangely he had pretty much no memory of it.
