15 days after conquering Manchester City, Liverpool has again faltered, this time losing to West Brom 3-2 in an entertaining and bizarre game.
In a game that saw Jay Rodriquez score twice, the game however was overshadowed by the video assistant referee (VAR).
After West Brom led 2-1 early in the first half, it appeared that West Brom had extended their lead, only before having it chalked off by the VAR.
Following this, the first ever on field referee review was used minutes later, as the referee used it to award Roberto Firmino a penalty, which consequently went on to hit the cross bar.
Later on in the half, West Brom had a pinch of luck with the VAR, which confirmed they had gone 3-1 up just before the half after a long deliberation from the VAR.
After the half-time interval, a Mo Salah goal wasn’t enough to overcome a defiant West Brom side, which became the first team to win at Anfield since April last year.
In a match that saw Alexis Sanchez make his Manchester United debut, the Red Devils saw off minnows Yeovil Town 4-0 in a one-sided contest.
It was evident however in the first half that Sanchez lost possession too often and easily, yet he was still able to provide assists for Marcus Rashford and Ander Herrera’s goals in a mixed but solid debut game for the star signing.
