A first defeat in 18 games, excluding penalty shootouts, leaves Frank Lampard's men still two points adrift of Tottenham and Liverpool at the top of the table.
They can extend that advantage to five points when they are in action on Sunday.
Victory lifts Everton up to seventh and within just one point of the top four.
