But Everton equalised four minutes later when 19-year-old defender Jarrad Branthwaite, in his first league appearance of the season, converted at the back post after Anthony Gordon's free-kick.

Thiago Silva had a chance to win it for the hosts but saw his powerful header superbly saved by Pickford.

The Spaniard had to make five changes from the weekend, with Demarai Gray, Salomon Rondon and Fabian Delph ruled out because of illness, while Richarlison and Andros Townsend had joined a lengthy injury list, which already included Dominic Calvert-Lewin, Tom Davies and Yerry Mina.

That led to Benitez handing a first-team debut to 20-year-old striker Ellis Simms, with Branthwaite making only his second Everton appearance.

Before the match, Chelsea boss Thomas Tuchel confirmed that strikers Romelu Lukaku and Timo Werner, as well as winger Callum Hudson-Odoi, had tested positive for Covid-19, while another forward, Kai Havertz, was also not in the squad while awaiting a Covid test result.

Chelsea missed those strikers as they were regularly frustrated by Pickford, with Mount and James shooting just wide and the impressive Hakim Ziyech narrowly missing the target on three occasions.

It was a similar situation after the break with Mount, Ruben Loftus-Cheek, Cesar Azpilicueta and Antonio Rudiger all missing chances as the home fans became restless.

Mount's goal settled their nerves but Everton showed superb character to equalise four minutes later with Gordon's free-kick from deep finding Branthwaite, sliding in, to snatch a leveller.

"We missed chances and struggled to find a high rhythm in the second half," Tuchel said.

"We didn't have anyone on the bench, we put the last guys in that we had available and we're missing big personalities and quality.

"Defensive was zero concerns, we conceded from a set-piece. I cannot break my head if we play like this in defence, they have zero chances to score but did from a free-kick."

It was an impressive performance from the England international as he also kept out earlier efforts from Christian Pulisic, James, Jorginho and three strikes from Mount when it was goalless.

"Jordan Pickford made some good saves, it is important to have a good goalkeeper," Everton boss Rafael Benitez said.

"Sometimes you need a bit of luck, this year we are not very lucky with all the injuries.

"Obviously, it is difficult to get points here but ... we did it with so many senior players not available and players on the bench still with some issues."

On Branthwaite's goal, Benitez added: "He's a good player, a young player who has the potential. We were practising set-pieces, so really pleased for him."

Two points dropped for Chelsea, but Everton fight hard for point

Chelsea, aiming to win the Premier League title for the first time since 2016-17, will be left wondering how they failed to get the three points in a match where they had 80% possession and had 23 shots.

The result leaves them third, four points behind leaders City, with Everton staying 14th.

But Benitez, back at Stamford Bridge after a spell as Chelsea manager in 2012-13, will have been delighted with the effort and desire from his Everton side, who were without 12 players because of injury or illness.
