Manchester United secured one of their most dramatic wins of Erik ten Hag's reign with a result that may well have saved the Dutchman's job at Old Trafford.
Despite finding themselves 17 points behind bitter rivals Liverpool in the Premier League table, the hosts wasted little time seizing the initiative and took an early lead through Scott McTominay.
A strong first half performance was dashed by back-to-back goals from Alexis Mac Allister and Mo Salah that put Jurgen Klopp's side firmly in the driving seat.
