Key player Australia: Clare Polkinghorne

Polkinghorne is set to play her 100th Matildas game if she gets on the field against Portugal tomorrow morning.

She is one of the most experienced defenders playing with the Matildas for the last 12 years.

Polkinghorne’s defensive skills are second to none, but she also possesses a cool head, knowing that a game is never won until it’s won.

Her early goal against Norway, and her “nudge for extra measure” on Larissa Crummer’s winning goal is a testament to her ability to make the most of every opportunity.

Where will it be won?

The current FIFA standings suggest a “David and Goliath” type match but in football anything is possible.

Australia will be favourites heading into the match but after they let Norway back into the game in the first round, they will need to ensure their defensive structure is working together.

Portugal did beat China PR in the opening round, which may have come as a surprise to some fans but China has not finished in the top four since 2010. They face one of the most feared attacks in the competition with Sam Kerr leading the charge.
