Emma Hayes was forced into an early and unexpected change as Sam Kerr came off injured for Chelsea in the 30th minute against Everton.
Kerr, who is just the second player to score 10 or more goals in three consecutive WSL seasons but was forced off just half an hour into their clash at Kingsmeadow.
She came off just minutes after scoring the second goal of the match which saw Chelsea lead Everton 5-0 at half time.
