The Matildas have had a difficult run-up to the Olympics, with several key players sidelined by injury.

Midfielder Katrina Gorry has been out after ankle surgery, defender Clare Hunt has battled a foot fracture, and stalwart Aivi Luik has a hamstring injury. Young midfielder Amy Sayer also tore her ACL last month and has been ruled out of the Olympics.

Before the send-off matches against China, Gustavsson said selection for the 18-strong Olympics squad had become a complicated equation – with some hopefuls racing against time to return to the field.

“This window will be a tough one for me and my staff in terms of evaluating players, where they are, and then the final selection process for Paris,” he said.

Kerr was expected to be an integral part of the Matildas medal campaign in Paris, after the team just missed the podium at the previous Olympics in Tokyo and the World Cup in Australia last year.

Since joining Chelsea in 2020, Kerr has won five successive Women’s Super League titles, three Women’s FA Cups, two Women’s League Cups and the Women’s Community Shield.

She has scored 99 goals for the Blues and a further 64 for Australia, and has also been nominated for the Ballon d’Or Feminin – the top prize in women’s football – every year since its inception in 2018.

But it has been a difficult 12 months for Kerr. She spent much of the home World Cup on the bench with a calf strain, and shortly after her ACL injury, was in January charged with racially aggravated harassment of a London police officer, to which she has pleaded not guilty.
