Chelsea suffered another setback in their Premier League title challenge when they were held to a 1-1 home draw by an injury-hit Everton on Thursday, leaving the Blues four points adrift of table-toppers Manchester City.
The hosts, themselves missing their first-choice strikers due to Covid-19, failed to turn early dominance into goals before Mason Mount made the breakthrough in the 70th minute when he took a pass from Reece James and fired past Jordan Pickford.
Mount had missed one of the hosts' many chances in the opening half when, clean through, he was denied by Pickford's outstretched foot.
The visitors drew level within four minutes of Chelsea going ahead when Anthony Gordon floated a looping free-kick to the far post and 19-year-old Jarrad Branthwaite stretched out a boot to turn the ball past goalkeeper Edouard Mendy.
Chelsea struggled to make further inroads without Romelu Lukaku, Timo Werner and Callum Hudson-Odoi, who had all tested positive for Covid.
Kai Havertz was also unwell and awaiting the result of a test.
The draw left Chelsea in third place behind Manchester City who thrashed Leeds United 7-0 on Tuesday, and Liverpool - who downed Newcastle at Anfield.
