Two errors from Alisson Becker contributed to Liverpool losing 4-1 to Manchester City at Anfield and further lose ground to the league leaders.
It was City’s first win at Anfield since 2003 to open up a five-point lead at the top of the table.
The usually flawless goalkeeper had a nightmare three minutes in the second half that put the game out of Liverpool’s reach.
Alisson is the first Liverpool goalkeeper to make two errors leading to a goal in a game since Loris Karius in the Champions League final.
The win took City’s tally to 50 points and are five points ahead of Manchester United with a game in hand.
City had the chance to broke the deadlock in the 36th minute when Raheem Sterling was felled in the box by the trailing leg of Fabinho.
Ilkay Gundogan stepped up to the spot, but fired his effort high over the bar.
Gundogan made up for his penalty miss by prodding in from close range in the 49th minute.
Raheem Sterling had breezed past Trent Alexander-Arnold before feeding Phil Foden who saw his shot expertly saved, but Alisson could only parry the ball into the path of Gundogan.
Liverpool was handed a major reprieve soon after when Mohamed Salah drew a penalty after getting the better of the otherwise faultless Ruben Dias.
The Portuguese hauled Salah down in the box, who himself converted the penalty to make it 1-1 on 63 minutes.
City went 2-1 up on 73 minutes after Alisson twice surrendered possession passing out from the back, with Foden beating two players before laying the go-ahead goal on a plate for Gundogan.
Lightning then struck twice as Alisson once again gave the ball away at the back. Bernardo Silva chipped the ball to the far post allowing Sterling to head home from less than a yard to make it 3-1.
In the 83rd minute Foden rounded off the rout as he fired a left-foot shot which flew past Alisson.
