At a time when most Australians will be curled up in bed, Sam Kerr will be changing the face of women's football once again.

Late on Sunday night (AEDT), the Matildas superstar will make her debut for Chelsea against Reading as the FA Women's Super League in England resumes after the Christmas break.

It's just one game, but it represents so much more. Kerr's arrival is being hailed in some quarters as a watershed moment for the English top division, which has never before been home to a player with such a huge reputation.

If Europe is emerging as the new power base of women's football, Kerr has landed herself in the eye of a brewing storm. Many believe the WSL will soon mirror the Premier League and become the best competition in the world, and it's easy to imagine how clubs such as Chelsea, Manchester City, Arsenal, Tottenham and others will be able to leverage the existing enormity of their brands and grow exponentially.
