Chelsea cruised past Everton to extend their lead at the top of the Women's Super League table to four points.
Jessie Fleming put the visitors ahead in the 14th minute with her first goal of the season, latching on to Clare Wheeler's poor clearance and volleying the ball into the bottom corner.
Sam Kerr doubled her side's advantage midway through the second half by poking Johanna Rytting Kaneryd's low cross past Everton goalkeeper Courtney Brosnan.
And the win was rounded off in the 90th minute when substitute Aggie Beever-Jones curled a superb strike into the top corner.
Business as usual despite Hayes announcement
The 47-year-old has been in charge of the Chelsea since 2012 and has guided the club to six WSL titles, including four in a row, as well as five FA Cups and two League Cups.
Despite so much noise surrounding the Chelsea camp, Hayes' team played with the same ruthlessness they showed against Villa, demonstrating a clinical edge that Everton were lacking.
They also went close through a Kerr header and an Erin Cuthbert shot from range before the break. And after the restart, they continued their dominance, deservedly adding two more goals.
The result means the Blues remain unbeaten in the WSL this season and on track for an unprecedented fifth consecutive title.
Everton's poor record against Chelsea continues
Everton's disappointing start to the season goes on. The Toffees have lost four of their opening six league fixtures.
The hosts have not beaten Chelsea since a 3-2 win in 2013, but they did create a handful of good chances in the first period.
Heather Payne, Martina Piemonte and Justine Vanhaevermaet all had shots which tested keeper Ann-Katrin Berger.
And Berger did brilliantly to keep out Sara Holmgaard in the 44th minute with a diving save. Vanhaevermaet then tapped home the rebound but Everton's equaliser was ruled out for offside.
Despite a strong opening period Brian Sorensen's side faded in the second half and were limited to sparse attacks on the break as Chelsea ultimately cantered to their win.
