The Baggies lost for the fourth time in five matches on Thursday night.
Two first-half goals from Alexis Sanchez put the Baggies to the sword, and dropped them to 15th place on goal difference.
West Brom had 29 per cent of the play and produced one shot on target to leave their tally of away wins at an alarming one in their last 12 trips.
Despite this, Tony Pulis' team are all-but safe from the relegation, with 10 points separating them and 18th-place Sunderland with four fixtures left to play.
However, their poor form - and for many, their poor season as a whole - has raised concerns over West Brom's ability to compete in next season's Premier League, particularly with Pulis at the helm.
The Welshman bore the brunt of the fans' frustrations after, with one even blaming him for the mass of empty seats at the Emirates Stadium.
Though some were a little more understanding.
This was the word on that there Twitter...
#wba trudging to relegation under Pulis. Football is a business & our product is awful. Those who ridicule the Villa beware.— Paul Wooding (@pazman1973) 22 April 2016
He may have kept us up last season and possibly (only) this but few can have done more to damage the image of our club than Pulis #wba— Steve (@pennwba) 22 April 2016
#wba, Pulis clutching defeat from the jaws of victory. Looks like he may drag us into the championship— Andrew Worsfold (@Drew48) 21 April 2016
First time we and I have played on a Thursday, what a load of bollocks Tony #wba— Ross Moran (@RossMoran) 21 April 2016
17 years a #wba season ticket holder but no way will I renew with Pulis at the helm. It's bloody awful. Football should be entertaining.— Peter Rollason (@PRollason) 21 April 2016
Now for some balance...
#wba I'd be the 1st to slate Pulis but let's have some perspective, Prem League again next season, 1 & only target for the season achieved— Nathan James (@nathy_james) 21 April 2016
It may not be perfect but at times we have shown real quality. With the right additions we will go further under Pulis. #WBA— Brad Poole (@BradPoole71) 21 April 2016
Look at the lineups on paper and tell me where this expected free flowing, attacking football is coming from? We're a rag tag outfit. #wba— Brad (@patterson_paddy) 21 April 2016
Yet the blame lies with Pulis? Baffling that people believe James McLean and Yacob could play flowing football if the shackles were off #wba— Brad (@patterson_paddy) 21 April 2016
