Liverpool goalkeeper Alisson Becker punched the ball in his own net for West Ham’s bizarre opener at the London Stadium.
After West Ham’s first attack saw Michail Antonio win a corner, Pablo Fornals curled one in from the left side.
And the flight of the ball was horribly misjudged by Alisson, who scored an own goal in the fifth minute.
The Brazilian appealed for a free-kick after falling to the turf and VAR checked for a foul on him – as well as a possible handball from Angelo Ogbonna – who had challenged the former AS Roma shot-stopper.
But the officials saw no error and the howler of a goal stood. Former Liverpool defender Jamie Carragher agreed with the decision and was critical of Alisson, feeling “it’s certainly enough” for a foul to be awarded.
Alisson, who was on the scoresheet at the right end for Liverpool against West Brom last term, became the second goalkeeper to score an own goal in the Premier League this term after Tim Krul vs Manchester City in August.
The own goal denied Alisson a 50th clean sheet in the Premier League for Liverpool.
In a fast and furious start to proceedings, Aaron Cresswell caught Liverpool skipper Jordan Henderson on the knee after a follow through challenge and VAR checked for a potential red card.
However, the process was over fairly quickly and play resumed without a yellow card or even a free-kick.
