Chelsea's unbeaten run of 17 games in all competitions came to an end at Goodison Park as Everton won 1-0, the home side claiming just their second win in eight games. The defeat for Frank Lampard's side means Chelsea missed the chance to go top of the league.
Gylfi Sigurdsson scored the only goal from the penalty spot after 22 minutes, following a foul by Edouard Mendy on Dominic Calvert-Lewin. Reece James had Chelsea's best chances to get back in the game but was twice denied by Jordan Pickford, and Chelsea were unable to break a resolute home back line that featured four central defenders.
