Heading into the match there had been a bit of banter going around between the US and Matildas players at their NWSL clubs. 

Despite the friendships players like Kerr have forged with their teammates, when they step out onto Dicks Good Sporting Park on Thursday evening (local time).

"In the change room at Chicago there was a bit of banter going on but come tomorrow there are no friends," she said.

"You kinda harder and your friends than anyone else but we both want to win. 

"I'm sure it's the same for all the girls in the team and their team but there'll be no friends tomorrow when we cross that line."

Having just finished their last training session in Colorado, Kerr expressed her excitement over the opportunity to face the top-ranked nation.

The last time the two sides met was during the 2018 Tournament of Nations and finished 1-1 after an injury time header from Lindsey Horan levelled the scores.

"We're excited," she said. 

"You always want to play the best teams and it is a good benchmark but at the end of the day, this is preparation for the World Cup and we're going to be focusing on ourselves.

"We hope that we can win but the most important thing is continuing the journey to improve to get to the World Cup."
