The Eastenders looked like they were staring down the barrel of yet another home defeat when James McClean’s effort sent the Baggies into the half-time break 1-0 ahead.
But David Moyes managed to rally his troops and they came roaring back in the second period – resulting in Carroll’s dramatic and decisive late strike.
The England international had levelled things up in the 59th minute with a trademark header, but he truly sent West Ham supporters absolutely crazy by managing to squeeze home this effort when 94 minutes had already been played:

Andy Carroll has scored more goals this year than Lukaku, Aguero, Kane and Morata combined and he didn't cost £90m

The result really piles the pressure on Alan Pardew, whilst David Moyes continues to restore some of his credibility at the London Stadium.
What do you think of the result, and are West Brom set for a relegation dogfight?
