Liverpool continue to dominate the Premier League after a lively weekend of surprise results and a relegation six pointer.
Virgil van Dijk scored a brace of first-half headers in eight minutes from Trent Alexander Arnold set pieces, which was enough for Liverpool to seal victory after Brighton halved their deficit late on.
Alisson was dismissed in the 76th minute after he handballed Leandro Trossard’s effort outside the box, consequently allowing Lewis Dunk to blast the resulting free-kick under the wall into the bottom left corner.
Leicester remain eight points behind the Reds after goals from Jamie Vardy and Kelechi Iheanacho overturned Richarlison’s headed opener for Everton, who now must visit Liverpool in midweek.
Manchester City twice blew their lead as Newcastle scraped an entertaining 2-2 draw, although the Citizens do stay third after Aaron Cresswell’s curler saw West Ham end a 14 match away hoodoo at Chelsea.
Tottenham climbed to fifth after taking a 3-2 victory at home to Bournemouth, in which Dele Alli and Harry Wilson scored braces for their respective teams.
Wolves and Sheffield United round out the top seven after Matt Doherty’s header cancelled out Lys Mousset’s second minute opener for the Blades.
Down at the bottom, Southampton came from behind to beat Watford after Danny Ings and James Ward-Prowse overturned Ismaila Sarr’s debut league goal for the Hornets.
That loss left Watford rock-bottom as Quique Sanchez Flores paid with his job on Sunday afternoon.
Norwich meanwhile sandwich the pair after holding a managerless Arsenal to a 2-2 draw, as Pierre-Emerick Aubameyang twice rescued the Gunners from defeat under Freddie Ljungberg following Unai Emery’s firing on Friday.
Elsewhere, Aston Villa snatched a point against ninth-placed Manchester United in a four goal thriller at Old Trafford.
Jack Grealish put the Villains ahead with a stunning 11th minute top right curler, only for Marcus Rashford’s header to go in off the back of a helpless Tom Heaton just minutes from half-time.
Victor Lindelof then headed United ahead from Wesley’s poor clearance of a cross but Villa were level just two minutes later, as Tyrone Mings volleys in Matt Targett’s cross to send them three points clear of the drop.
Finally, clinical strikes from Wilfried Zaha and Jeffrey Schlupp saw Crystal Palace take victory at Burnley to end a three match losing streak.
