Wretched Arsenal taste defeat away from home for the third league match running.
They have now lost four out of five top-flight games for the very first time under Wenger. It is impossible to envisage a situation where the long-serving Frenchman continues in his current role beyond the summer.
The Gunners were defensively inept, but that should not detract from a marvellous victory for West Brom. The Baggies know their strengths and utilised them well to match their 43-point tally from 2015-16.
West Brom 3-1 Arsenal
With the last kick of the game, Ramsey launches a woeful shot high and wide.
That just about sums it up.
Field, in behind the Arsenal backline, shows commendable maturity to head to the corner flag instead of trying to extend West Brom's lead even further.
He is eventually dispossessed by Monreal.
Good defending from Field to head away Iwobi's cross at the near post.
18-year-old academy graduate Sam Field comes on for West Brom with two minutes remaining.
He replaces Chadli.
Many Arsenal supporters are filmed making their way to the exits as Mustafi fails to trouble Foster.
You can hardly blame them.
Chants of 'Ole' ring around The Hawthorns as West Brom stroke the ball around with ease.
Arsenal look beaten and listless. This is turning into another harrowing afternoon for Wenger, who will surely not be offered a contract extension.
Sanchez, clearly not 100% after that first-half challenge from McClean, makes way for Alex Iwobi.
It's safe to say that third and final change has not been well received by the exasperated away fans.
Wenger spoke about West Brom's enormous set-piece threat before kick-off, but it appears that those concerns did not filter down to his team.
Dawson is again the benefactor of more lazy marking, brushing past Oxlade-Chamberlain and emphatically heading McClean's corner beyond the helpless Ospina.
Arsenal just do not learn.
Goal: West Brom 3-1 Arsenal (Craig Dawson)
Pulis sends on Yacob in place of Brunt.
Under 20 minutes remaining for West Brom to hold on and secure back-to-back home wins against Arsenal for the first time since the 1950s.
A scrambling Ospina just does enough to deny Robson-Kanu his second goal of the afternoon. Mustafi then crucially blocks from Chadli and Brunt blazes a shot into row z.
Xhaka's corner is headed against the crossbar by Welbeck and Mustafi goes down under the challenge of Robson-Kanu.
Walcott wins a corner and is then quickly replaced by Giroud.
McClean, clearly standing in an offside position, wisely chose not to interfere there and instead let the ball run through his legs.
The Arsenal defenders and Wenger appeal angrily for a flag, but the goal is confirmed after a brief discussion between the referee and his assistant on the far side.
Talk about a swift impact. Robson-Kanu, much-maligned for his lack of scoring prowess at Reading, restores West Brom's lead just 74 seconds after coming on.
The Wales favourite prods home after Ospina fails to clear up following an attempted one-two between McClean and Chadli.
Goal: West Brom 2-1 Arsenal (Hal Robson-Kanu)
Having failed to end his recent goal drought, Rondon makes way for Robson-Kanu just nine minutes after the interval.
A shake of the head and a quick return to the dressing room rather suggests that he might be injured.
Rondon gets up above Koscielny to nod an exquisite left-wing Brunt cross wide. What a chance.
Just moments before, West Brom were forced to clear their lines after good play from the otherwise anonymous Walcott led to a corner.
Sanchez complains bitterly to the referee after a tussle with Dawson. That knock certainly does not seem to have diluted his competitive spirit.
Sanchez emerges for the second period at The Hawthorns. Given how poorly he was moving towards the end of the first half, that is something of a surprise.
Let's see how long he lasts.
They simply cannot afford to lose him...
