Scotland women's head coach Anna Signeul is pleased with the competition for places in her squad but insists the group still has room to develop.
Signeul has called up two uncapped player for the World Cup play-off semi-final against the Netherlands.
Hibernian midfielder Elizabeth Arnot and Spartans goalkeeper Rachel Harrison are included in the 20-strong squad.
"Competition in certain places is very tough and in others, we would like a little bit more still," said Signeul.
"If you look at the squad now and the squad nine years ago when I came, there's not many players left.

|"They are a very good team. They are very fast but we are really seeing that we have an opportunity to win these games"|
"We have changed a lot of players and taken in new players every year so the squad is developing all the time.
"Lizzie Arnold is a coming star. She's already doing fantastically well in the Under-19s. She's doing well at Hibs so if she's coming up, she's there to fight for a place in the starting 11.
"They are so ambitious. I'm especially proud of all the young players as well.
"They are putting in 10, 15 hours a week to progress as football players. I always thought we had great technical players in this country but I think that we show now that we are trying to play good football."
Glasgow City captain and midfielder but Leanne Ross is missing through injury but Turbine Potsdam forward Lisa Evans returns as the Scots bid to reach next year's finals in Canada.
Italy and Ukraine contest the other semi-final.
"It's a fantastic opportunity we now have to go to the World Cup and we have huge respect for Holland," explained Signeul.
"They are a very good team. They are very fast but we are really seeing that we have an opportunity to win these games.
"It's total football [from the Dutch]. This team has mostly played a 4-2-3-1. Their four attacking players are fast, very fast.
"Manon Melis is probably one of the fastest players in the world. She plays on the right side. They're very direct. It's going to be tough."
