Alisson Becker was the hero at the Hawthorns as the Liverpool goalkeeper helped the Reds to claim the three points at stake in the on West Brom.
The Sam Allardyce side looked to have denied the Reds a vital victory on Sunday and even had a winner of their own denied by a harsh offside call.
The Reds then laid siege to the Hawthorns goal and goalkeeper Alisson rose highest to meet a 95th-minute corner and earn a famous three points, thereby becoming an unlikely hero, Alisson.
It was surely the Reds’ final chance to snatch the win and so it proved as Alisson rose to glance Trent Alexander-Arnold’s delivery into the far corner of the net to send the away side into delirium.
In an example of extraordinary timing, it is the first occasion in which a goalkeeper has scored a competitive goal for Liverpool in their entire history, dating back to 1892.
The stunning moment takes the Reds just a point and a place behind Chelsea in fourth and three points worse off than third-placed Leicester with two games to go.
That the Blues and Foxes face each other in their next league game gives Jurgen Klopp’s side a huge opportunity to take control of their own destiny in the race for Champions League qualification when they travel to Burnley on Wednesday.
Things had got off to a terrible start for the reigning champions at the Hawthorns with Hal Robson-Kanu capping his first Premier League start since December 2017 with a neat side-foot finish to give West Brom the lead.
A typically incisive Mohamed Salah finish brought the visitors level, with the Egyptian’s low shot inside the far post taking him to 22 goals for the season, level with Harry Kane at the top of the scoring charts.
With Roberto Firmino firing against the woodwork, Sadio Mane seeing a finish ruled out for offside and others profligate in front of goal, it looked as though the Reds had blown their chance.
The Brazilian goalkeeper popped up with a stunning last-minute winner to earn Liverpool a huge boost in the race for the Champions League.
