The two strikes put Kerr seven goals ahead of her nearest competition in the NWSL goal-scoring charts, North Carolina Courage's Lynn Williams.

The win moves Chicago to within six points of the Courage at the top of the NWSL table, with Kerr accounting for over half of her side's goals this campaign.

The Australian has started every match that she's played this season and has only been withdrawn twice, a credit to her stamina and longevity at this level.

The record-breaking season as Kerr enters her physical peak at 26-years-old follows a prolific personal record at the World Cup and now stands her among the top two goal scorers in the world on a goals-per-game basis.

How long Kerr will remain in the NWSL is uncertain however, with rumoured links to the English Super League with Chelsea, and a myriad of European clubs sure to be circling in the rapidly approaching off-season.

“It’s not easy and these girls make it a lot easier than it should be,” Kerr said. “It was an amazing moment for me and something I’ll remember forever. It was nice to do it in front of the Chicago crowd," Kerr said.

“It was her record anyway, right?” Red Stars coach Rory Dames quipped sarcastically.

“Sam is special. It’s not a secret to anybody. I’m happy for her. She was excited so we’re excited for her, but Sam has bigger fish to fry this year than how many goals she scores.”
