PREM: Watford 0-3 Liverpool

Liverpool players celebrate Trent Alexander-Arnold’s stunning free-kick

Jordan Henderson will miss next week's Merseyside derby after being sent off as Liverpool beat Watford 3-0 in the Premier League on Saturday.

Henderson returned from injury as one of two changes made by Jurgen Klopp, but was given his marching orders in the 82nd minute after picking up a second yellow card, meaning he will be suspended for the game against Everton next Sunday, live on Sky Sports.

But the Reds remain unbeaten in the league and kept a clean sheet, with Mohamed Salah (67) opening the scoring before Trent Alexander-Arnold (76) added the second with a wonderful free-kick.

Roberto Firmino (89) scored late on after a devastating Liverpool counter-attack, and it sees them keep pace at the top with Manchester City, who beat West Ham on Saturday, while Watford slip down to ninth place.

Watford had the ball in the net inside three minutes but the goal was ruled out for offside. A long ball was touched on by Troy Deeney, allowing Gerard Deulofeu to race through but, as he slotted past Alisson, the offside flag was correctly raised.

The game was meandering towards the break until a flurry of late efforts. It began in the 39th minute as Salah latched onto a loose ball and slotted it into the path of Firmino, but his shot - the first on target in the game - was saved by Ben Foster.

Alisson was then called into action as Deulofeu played the ball across for Roberto Pereyra, but his curling effort was saved by the leaping Liverpool goalkeeper.

Xherdan Shaqiri was superb for the Reds in the first half, and another wonderful ball into the area picked out Sadio Mane who poked the ball towards goal, but Foster turned it behind for a corner. Shaqiri's subsequent effort found an unmarked Salah by the back post, but the Watford stopper did well to save the Egyptian's header.

Liverpool broke the deadlock in the 67th minute with another goal for Salah against Watford - his sixth in three games. Firmino slipped the ball to Mane down the left before he cut it back for Salah and the Egyptian then swept past Foster, who should have done better.

But Foster could do nothing about Liverpool's wonderful second from Alexander-Arnold. The 20-year-old lined up a free kick in the 76th minute as Firmino was pulled down by Adrian Mariappa 30 yards out, and curled a beautiful effort into the top corner.

Six minutes later, though, Liverpool were down to 10 men. Having been booked for a push on Isaac Success on the hour mark and a number of remonstrations with referee Jon Moss, Henderson was already on thin ice. But a foul on Etienne Capoue sealed his fate as he made his way down the tunnel before Moss could get the card out of his pocket.

Watford looked to take advantage of their extra man but it proved to be their undoing for the third goal as Liverpool hit them on the break. Andrew Robertson strode down the left flank before cutting the ball into the area for Mane, whose shot was saved by Foster, but the rebound was nodded home by Firmino.
