Elsewhere, Manchester City eked out a hard-fought 1-0 win over Arsenal later, Chelsea and Southampton shared a 3-3 draw at Stamford Bridge and three late goals earned Manchester United a flattering 4-1 victory at Newcastle.

In the day's big Mersey derby, Liverpool captain Henderson thought he had scored an injury-time winner but his strike that looped over Everton goalkeeper Jordan Pickford was controversially ruled out for a marginal offside by the video assistant referee (VAR).

"We don't understand why it's offside," said frustrated Liverpool boss Jurgen Klopp, who later asked the Premier League to review footage of the incident along with a later clash involving defender Virgil van Dijk and everton goalkeeper Jordan Pickford.

Sadio Mane, who made his return to the Liverpool line-up after recovering from coronavirus, struck the opener before Everton defender Michael Keane's 19th-minute header saw the city rivals all square at half-time.

Mo Salah restored the visitors' lead in the 72nd minute as he collected his 100th Liverpool goal with a snapshot volley, but Dominic Calvert-Lewin continued his scoring streak to salvage a point for Everton nine minutes from the final whistle.

Everton finished the match with 10 men after Richarlison was sent off late on for a challenge on Liverpool's Spanish midfielder Thiago.

The Blues were fortunate not to have received a red card sooner, after Pickford clattered into Virgil van Dijk, ruling the Dutch defender out for the rest of the game.

Manchester City had been missing star midfielder Kevin De Bruyne because of injury, but welcomed back key striker Sergio Aguero. The team's all-time record scorer played 65 minutes in his first match since June.

Raheem Sterling proved their match-winner, slotting a rebound into an empty net in the 23rd minute after City midfielder Phil Foden had a shot parried away by Arsenal goalkeeper Bernd Leno.

Chelsea will rue another missed chance after Timo Werner netted twice to put them 2-0 up and fellow new signing Kai Havertz later added a third against Southampton.

But strikes from Danny Ings, Che Adams and a late header from Jannik Vestergaard earned the Saints a share of the points.

Manchester United could have been forgiven for thinking it was not their day when, after falling behind to a Luke Shaw own goal in the second minute, Bruno Fernandes missed an early penalty.

But troubled central defender Harry Maguire levelled the scores after 23 minutes before a late flurry of goals from Fernandes (86), Aaron Wan-Bissaka (90) and Marcus Rashford (six minutes into added time) gave the scoreline a flattering look.
