The new Women's Super League marks the start of a new era for reigning champions Chelsea, with long-serving boss Emma Hayes having departed in summer to start a new adventure with the USA Women's team.
Last year they just about did enough to claim the title on goal difference ahead of Manchester City, while Arsenal will again hope to make it a three-horse race for the WSL title. Meanwhile Liverpool, Manchester United and Tottenham will hope to progress after further rebuilding this summer.
Crystal Palace were promoted to replace Bristol City in the top flight, while on a wider note, the league is now under the management and operation of a new organisation set up to lead women's football towards further growth and progression, with Nikki Doucet overseeing both the WSL and Championship in a new phase for the game.
