But there's no doubting who the entertainers are with the most high-powered attack.

Liverpool hit four goals for a third consecutive game by beating cross-city rivals Everton 4-1 on Wednesday, taking the team's scoring tally to 43 in 14 games - the most in a major European league so far.

Juergen Klopp's 2020 champions remained in third, but with another 24 games to go that's far from a concern.

On a rare occasion when the front-runners were playing at the same time, Manchester City won 2-0 at Aston Villa to stay a point ahead of Liverpool in second and Chelsea remain a point better off at the top after having the most challenging assignment by beating Watford 2-1.

The top three pulled away from fourth place after West Ham were held 1-1 by Brighton.

Leicester and Southampton also drew 2-2, while the meeting between Wolverhampton and Burnley was goalless.

Mohamed Salah is fronting Liverpool's scoring charge and he now has 19 goals in as many appearances this season in all competitions after his double at Goodison Park.

After captain Jordan Henderson gave Liverpool the lead in the Merseyside derby by shooting from the edge of the area, Salah's first goal was a curling shot across goalkeeper Jordan Pickford in the 19th minute.

Everton had the chance of a comeback after Demarai Gray pulled a goal back just before halftime. But Salah seized on bad error by Everton captain Seamus Coleman to race from halfway before striking into the net in the 64th.

Diogo Jota beat Pickford's near post for Liverpool's fourth as Everton's winless run extended to eight matches, with just two points from a possible 24.

Some Everton fans streamed for the exits after Jota's goal. Others stayed and directed their anger toward the directors' box after the final whistle. There were chants of "sack the board" as well as boos at the final whistle.

Former Liverpool captain Steven Gerrard couldn't help out his old team in his third game in charge of Aston Villa.

Bernardo Silva's volley from Gabriel Jesus' cross followed Ruben Dias' goal for Manchester City in the first half at Villa Park.

Ollie Watkins reduced the deficit in the 47th with a first-time finish off a corner to the near post but City held on, helped by the second-half introduction of Jack Grealish - the boyhood Villa fan and former club captain who left for a British-record fee of $A196 million in the offseason.

Hakim Ziyech scored his first league goal of the season to clinch Chelsea's 2-1 win at Watford in a match that was halted for 32 minutes in the first half after a spectator suffered cardiac arrest.

The substitute converted a cross in the 72nd from Mason Mount, who had put Chelsea in front in the first half before Emmanuel Dennis equalised.
