Fran Kirby and Ji So-yun scored either side of half-time as champions Chelsea moved to the top of Women's Super League with a comfortable 2-0 victory at mid-table Birmingham.
League top-scorer Kirby gave the visitors a 19th-minute lead in Solihull, converting a rebound from close range to claim her 12th goal of the season after Crystal Dunn's initial effort was blocked.
South Korea midfielder Ji struck a delightful left-footed shot into the top right corner from the edge of the box to double the advantage 19 minutes from time.
With Manchester City not in action until Sunday, the result leaves Emma Hayes' unbeaten side a point above their title rivals, albeit having played a game more.
