‘The Reds’ entered into this clash as the only team yet to lose a league game this season, as they are unbeaten in 20 league games spanning up from last season.
Liverpool, who scored within the opening 10minutes in their last three premier league games, saw themselves behind in the fourth minute.
Pablo Fornal’s corner was diverted in by Alisson, who was under pressure from Angel Ogbona. After VAR review for a possible foul on the goalkeeper, the goal stands.
As expected, Liverpool dominated possession while in search of an equaliser.
They eventually were able to break down the ‘Hammers’ defence in the 41st minute when Trent Alexander-Arnold whipped in a curler of a free-kick after Salah was fouled at the edge of the box.
The England right-back gave Luckasz Fanbiaski no chance as it ended in a stalemate into halftime.
