Liverpool captain Jordan Henderson will miss the Merseyside derby after picking up a red card in a 3-0 win over Watford.
Henderson was cautioned with a yellow earlier in the match but brought down Etienne Capoue with nine minutes remaining.
His ill-disciplined sending off may have limited the team to 10 men, but it posed no serious consequences on the result.
Goals from Mohamed Salah, Roberto Firmino and Trent Alexander-Arnold secured victory for Jurgen Klopp’s men.
The Reds are now two points off first-placed Manchester City and have kept their undefeated streak alive.
Liverpool’s line-up saw Xherdan Shaqiri earn another start as he played on the right wing of Klopp’s 4-2-3-1 formation.
He was clearly the team’s bright spark, opening up play and ushering his teammates forward.
His cross to Salah in the box midway through the half and his chip to Georginio Wijnaldum were the highlights from the first 45.
Liverpool couldn’t seem to consistently build up an effective attack. They were content keeping possession without much forward movement and as a result, invited Watford to counter.
Fortunately, Alisson Becker’s diving save off a Roberto Pereyra close-ranged shot in the 39th minute was as close as the home side got to scoring.
Penalty shout aside, Watford were a different group in the second half. They absorbed more pressure than they should have allowed.
As a result, Mané was able to break on the left flank and send a strong cross to Salah for a 10-yard finish.
Salah has now scored more goals against Watford than any other side in his career. Saturday’s strike is Salah’s sixth in 186 minutes against the Hornets.
About 10 minutes later, Trent walloped a perfectly-placed 20-yard free kick into the top right corner.
Henderson’s red card may have been rash but it didn’t seem to affect the game.
Firmino put the game to bed moments later with a quick header off a deflected save from Ben Foster.
The win means Liverpool have secured their best start to a Premier League season with 33 points from 13 games.
Tottenham’s domination of Chelsea also means Liverpool have strengthened their hold of second place in the table.
The Merseyside club will go into their Champions League tie against PSG in good spirit but could be without Joe Gomez for another game. The defender picked up a small ankle injury in training.
