Bolger tips bright future for Matildas

Just how good this Matildas group can become is scary to think about for Australia midfielder Nicola Bolger.

The average age of Alen Stajcic's squad is 23.8, with the likes of Katrina Gorry (22), Emily van Egmond (21), Caitlin Foord (20) and Steph Catley (21) all younger than that.

The Matildas became the first Australian team – male or female – to win a match in the knockout stages of a World Cup with their victory over Brazil.

And Bolger, 22, is excited by what the future holds.

"It's kind of freaky, I think," she said.

"We come off the field in our previous performances and think we've done good, we got the job done but we still know there's so much room even, I don't like to say beyond this World Cup, but it is quite scary to think.

"We've got so much depth, so much talent and so much belief so hopefully we can just continue to grow in this tournament and hopefully on Saturday it's an even better performance."

The Matildas will face either Japan or the Netherlands in the World Cup quarter-finals on Sunday morning (AEST).

Forward Ashleigh Sykes agreed with Bolger, and coach Stajcic, that Australia will get better.

"I'm not sure we've played it [our best game] yet, to be honest," she said.

"We've had patches and things like that where we've played really good football, the football we want to play. Defensively, it was probably one of our better games as well [against Brazil].

"I think different parts of our game keep growing as we go along.

"Hopefully we can only get better because it's getting to the pointy end of the competition so you have to be at your best really."
