Darwin Nunez headed in a dramatic 99th-minute winner for Liverpool to beat Nottingham Forest 1-0 amid chaotic scenes at the City Ground.
Forest had fought hard throughout and had chances to win it themselves at the City Ground but failed to clear one final corner and Nunez, on as a substitute, headed in Alexis Mac Allister's deep cross to spark wild scenes of celebration in the away end.
Jurgen Klopp's side remain depleted by injuries but this could prove a pivotal moment in the title race. Had they failed to score, they could have found themselves third by Monday evening. Instead, they finish the day four points clear of Manchester City.
For Forest, there was huge frustration given that the ball had been returned to Liverpool shortly before the decisive goal went in, following a head injury with them in possession. Evangelos Marinakis, the Forest chairman, appeared pitch-side as others remonstrated with the officials.
