Birmingham v Arsenal (14:00 GMT)
The postponement of Chelsea's game against Tottenham on Friday means WSL leaders Arsenal can move seven points clear at the summit with victory against bottom side Birmingham City today.
Blues boss Darren Carter wants his players to remain "positive" and to to "impose themselves" on the competition pacesetters.
"Every team has their weaknesses, of course. Arsenal are a team that play very expansive, are very good with the ball and rotate in the middle area of the pitch," he said.
"But we think we can identify a few things that can pose them a question. They dominate games but there are times you can go at them. I will never be a coach or a manager that soaks up pressure.
"I want us to attack games and impose ourselves."
