Kerr explains where Westfield Matildas must improve after Chile upset

Star striker Sam Kerr pinpointed wastefulness in attack as prompting the Westfield Matildas' downfall in the 3-2 loss to Chile on Saturday.

Emily van Egmond's early penalty was wiped out by Francisca Lara and Carla Guerrero before Yessenia Huenteo scored late to condemn Australia to a rare home defeat.

REPORT: Clinical Chile spring surprise on Westfield Matildas

Van Egmond completed her brace with a second spot-kick in stoppage time but it was an otherwise frustrating afternoon in attack as Kerr and company found Christiane Endler in top form.

The Paris Saint-Germain goalkeeper made a number of smart saves as Chile's desperation in defence helped set the platform for a clinical counter-attacking display.

"Obviously you want to win all the time but we probably just conceded a few too many goals and weren't good enough in the front line," Kerr told Fox Sports.

"That's on us forwards. It's something to work on.

"[Chile's time-wasting] is frustrating. You want to play as much as you can, but that's part of the game and you see that everywhere in football.

"It's our fault for not taking our chances and letting them take the time away."

The defeat was the Westfield Matildas' first on home soil since 2014.

Kerr and her and team-mates have the chance to exact revenge when the teams reconvene for the second of the two-match Seven Consulting International Series in Newcastle on Tuesday night.
