When Kerr joined Chelsea, it was the biggest transfer an English club had made.
She was a global superstar who had broken goalscoring records in each league she had played in, and was an icon back in Australia.
Her stock has only increased during her time in England as she helped Chelsea become the most dominant club of the past decade.
Known for her backflip celebrations, Kerr has scored some of Chelsea’s biggest goals in FA Cups finals and Champions League knockout games.
Under former manager Emma Hayes, she was the star player in the team, and built a formidable partnership with playmaker Fran Kirby during Chelsea’s six-year stranglehold of the WSL.
Her two-year absence more recently, following an ACL injury, forced Chelsea to look elsewhere for attacking options and current manager Sonia Bompastor has not been able to call on Kerr for much of her time in charge.
However, Kerr’s return to full fitness for the second half of this season – and six goals in her past six games in all competitions – showed what she is still capable of and why she remains one of the world’s best strikers.
She is irreplaceable at Chelsea but Bompastor has already confirmed buying a number nine is high on the club’s priority list for the summer.
Manchester City’s top-scorer Khadija Shaw is top of Chelsea’s wish list but whoever they sign to replace Kerr will have enormous boots to fill.
Kerr’s future is unknown though sources close to the player have suggested a return to the National Women’s Soccer League in the United States is on the cards.
Australian broadcaster 10 News reported in April that Kerr had agreed a move to Denver Summit but the striker quickly dismissed it on social media.
