Gylfi Sigurdsson's 80th-minute strike earned Everton a fourth consecutive victory as they moved up to second place with a 1-0 win at Sheffield United.
Abdoulaye Doucoure teed up Sigurdsson, who took a touch before drilling a low shot into the bottom-left corner to clinch all three points.
Dominic Calvert-Lewin and Sigurdsson both fired narrowly off target during the first half, while Oliver Burke shot inches wide for Sheff Utd.
Enda Stevens lashed over the crossbar and substitute Oliver McBurnie missed an opportunity as Sheff Utd pushed for a late equaliser.
Everton kept their hosts at bay to move up to 29 points, two behind leaders Liverpool who have a match in hand at West Bromwich Albion on Sunday.
Sheff Utd remain bottom of the table on two points.
