The visitors started brightly and took the lead in the sixth minute through Kerr. Erin Cuthbert delivered a perfectly timed through ball that split the Everton defence, and Kerr applied a composed finish to give Chelsea an early advantage.
However, the lead lasted only four minutes as Everton responded through Yuka Momiki, who produced a stunning strike from 35 yards after spotting goalkeeper Hannah Hampton off her line, with Clare Wheeler providing the assist.
Chelsea controlled possession for much of the first half but were unable to convert their dominance into further goals. Courtney Brosnan made important saves to deny efforts from Keira Walsh, Alyssa Thompson and Sjoeke Nusken, ensuring the sides went into the interval level at 1-1.
The second half saw Chelsea assert their authority and take control of the contest. Just two minutes after the restart, Kerr restored the lead, finishing first-time from the left side of the area after an inch-perfect pass from Lauren James. Moments earlier, Everton had come close to going ahead themselves, with Maz Pacheco diverting a cross from Toni Payne onto the crossbar from close range.
Chelsea extended their advantage in the 53rd minute when Ellie Carpenter saw her effort deflect over Brosnan after a delivery from Alyssa Thompson. Kerr pushed for a hat-trick and came close, but Pacheco produced a crucial goal-line clearance to deny her.
The visitors continued to dominate proceedings and added a fourth goal in the 70th minute. After Kerr’s header was blocked, Cuthbert reacted quickest to fire a half-volley from the edge of the box beyond Brosnan, sealing a comprehensive win for Chelsea.
Sam Kerr was named player of the match following her impressive performance in the match.
