Ahead of a quarterfinal against Japan, Australia is worried about the Women's World Cup's heat-absorbing pitches.
Australia striker Michelle Heyman has compared playing on the artificial pitches at the Women's World Cup to "walking on hot coal".
The synthetic turf in use in Canada has been a topic of controversy both in the lead up to the World Cup and during the tournament, with players complaining of the added injuries they are suffering because games are not being played on grass.
"It's like you can't really get grip on your feet and your feet keep sliding around in your boots because they're that hot and kind of sweaty," Heyman told the Sydney Morning Herald on Thursday.
