Beth Mead scored twice as Arsenal moved top of the Women’s Super League with a resounding victory at Liverpool.
Kim Little guided in Katie McCabe’s low cross and Mead added a second for Arsenal when her strike squeezed past Anke Preuss and was eventually given.
The visitors led 3-0 when Mead’s mishit cross floated in at the far post, with Dominique Bloodworth heading a fourth.
Courtney Sweetman-Kirk’s penalty gave Liverpool a consolation before Vivianne Miedema netted late on for the Gunners.
Joe Montemurro’s Arsenal are a point clear with a game in hand on title rivals Manchester City, who they face on the final day of the season.
Liverpool keeper Preuss will be disappointed with each of Arsenal’s first two goals, Little’s finish bobbling over her outstretched hand and England striker Mead beating her at her near post from an angle.
Mead’s first was not initially awarded by the assistant, but was given by the referee once it was established the ball had gone the right side of the post.
Her second was similar to the goal she scored for England against Brazil in the SheBelieves Cup last month, though on this occasion Mead was trying to find a team-mate in the box.
Arsenal need nine points from their final four matches for their first WSL title since 2012, meaning they will be champions by the time they play City on 12 May if they win their next three games.
