Head to Head RecordSarri's side have won 73 of their previous 179 encounters with Everton, the Toffees have overcome their hosts on 54 occasions, and will be determined to close that gap on Sunday.
If recent encounters between the two sides are anything to go by, Sunday's game is likely to be a stroll for Chelsea, with the Blues having won four of their last five matches against the Toffees, including a 5-0 rout back in 2016 when Eden Hazard netting twice.
Recent FormChelsea's early season form has been nothing short of sensational; they remain unbeaten in the league along with Manchester City and Liverpool.
Successive draws to West Ham and Liverpool had seemingly halted the Blues flawless opening to the season, though to their credit Sarri's players have bounced back and won three of their last four league games in convincing fashion.
Marco Silva has seemingly settled on a system that, for the time being at least, works well for his players after a summer of significant recruitment at Goodison Park.
Summer signings Andre Gomes, Bernard and Richarlison have given Silva's side dynamism in midfield and attack while Lucas Digne and fellow Frenchman Kurt Zouma have brought youth and pace to an ageing defence.
Gylfi Sigurdsson will be the man to watch for Chelsea's defence on Sunday, with the Icelandic international looking back to his lively up best in recent weeks. He will still feel that he has a point to prove on Merseyside, having set the Toffees back £40m when signing from Swansea last summer.
