Chelsea’s 17-match unbeaten run was ended by an Edouard Mendy error at Goodison Park as a patched-up Everton side won 1-0 to deny their visitors the chance of going top of the table.
The Blues goalkeeper, bought this season to replace the unconvincing Kepa Arrizabalaga, clumsily brought down Dominic Calvert-Lewin which allowed Gylfi Sigurdsson to score the decisive 22nd-minute penalty.
