Williams welcomes competition for Westfield Matildas' number one shirt

Westfield Matildas goalkeeper Lydia Williams is relishing the healthy competition provided by positional rival Mackenzie Arnold.

Widely regarded as among the best shot-stoppers in the world, Williams has been Australia's undisputed number one at the last two international tournaments.

But the impressive development of Brisbane Roar goalkeeper Arnold and experience of squad member Casey Dumont means there are no guarantees for the upcoming AFC Women's Asian Cup.

"In the last couple of years we've changed the way we want to play, especially from the goalkeeping standpoint," Williams explained to matildas.footballaustralia.com.au.

"We want to use our feet a lot and play out. [Mackenzie] is one of the most technical goalkeepers Australia has produced.

"It's nice we've been able to push each other and be encouraging at the same time.

"While it's a competition, it's also a really good friendship and respect for each other."

The Westfield Matildas head to Jordan on the back of a lengthy training camp in Perth culminating in a big friendly victory over Thailand.

Melbourne City star Williams believes the time spent locally will be beneficial come the Asian Cup.

"It's been a little bit different. A lot of the time we're based overseas with our preparation," she said.

"It's been nice to have some familiarity and be a little bit closer to home since most of us don't get to spend a lot of time in Australia.

"We've been pretty lucky we've been able to have the whole squad together.

"I think being in Perth is pretty similar to what the weather might be like in Jordan. It's been good."
