City was the first team to win all their regular season games in the previous campaign eventually defeating Sydney FC 4-1 in the 2016 grand final.

Williams’ strenuous schedule continues after completing her season in the US with Houston Dash, as well as commitments to the national team’s Olympics campaign in August.

The goalkeeper adds to the spread of experience in City’s squad with Matildas Lisa De Vanna, Steph Catley, Larissa Crummer, Laura Alleway and Teigen Allen.

She brings big match nous after winning the 2012 W-League Championship with Canberra United and believes City can replicate such success in the domestic competition.

“The quality of the players and the leadership we have in this team. I think it’s very exciting, we can definitely do the double,” Williams told FourFourTwo.

“I think they kept the majority of their (City) signings and I think the way they approached the league last year, other teams want to make it more competitive, if not just as competitive, so I think the season is going to be a step up.

“Being overseas as well, this setup is probably the most professional that I’ve been in or witnessed as well. The way they’re leading women’s sport and women’s football I think is not only in Australia, but around the world is a testament to how they run the club.

“We get to be in the same area as the men and use the same facilities and everything, so I think it’s fantastic. Obviously they want to keep, no matter if you’re male or female everyone is professional, so I think that’s the best thing about it.”

Allen, who played in the recent grand final with former club Sydney FC, said she was also impressed with the club's environment.

“In comparison to Sydney FC, I think this is one of the most professional clubs especially being connected with Manchester City,” Allen told FourFourTwo.

 “I’m definitely looking forward to a good season with them and I couldn’t’ be happier at the moment. I’ve only been here for three weeks, I still haven’t seen everything, but I’m not disappointed, everything is up to an amazing standard and very professional.”

Williams played 14 of the 20 games of Houston’s 2016 NWSL season and made four appearances for the Matildas in the Rio Olympics.

She said the involvement of American women in US national team was growing the domestic league.

And while she admitted the depth of US football was better, she said Australian women’s football was providing more “creativity and flair”.

“There’s a difference where coming from that league (NWSL), they want results and they want the game to go their way where you come to W-League, they want to develop, they want to grow the game,” Williams said.

“I get excited coming back here where I can really work on things I maybe wasn’t able to work on overseas and I think the way football is getting played in Australia, we want to play, we want to learn and grow the game.

“You can tell by us being the most played women’s sport at junior levels we are putting on the entertainment level and we’re getting closer and closer to the men’s game which I really enjoy and like coming back here being in Australia.”

 Australia had an oridinary Olympic campaign managing just one win from four games.

They still managed to book a place against Brazil in Belo Horizonte which saw host nation break Australia’s hearts after a 7-6 extra-time win in the shootout.

And while the Matildas returned disappointed, Williams was confidence the squad could maintain a high ranking and claim some silverware soon.

“I think we’re building depth, obviously the girls that have been starting have been around for quite a long time, playing with and against each other for many years from their 20s up until now, so we have quite a good understanding,” she said.

“I think it’s the job of the coaching staff for any new players who come in to quickly find their step and get in the rhythm.

“You can tell when we play together, everyone’s got a good understanding of each other and they’re really trying to build that depth and make sure the team we have can be around for a long time.”

Williams and her new teammates recently ran a coaching clinic in suburban Victoria mentoring children and teenagers.

She said such initiatives would greatly benefit the code in the AFL-mad state. 

“It’s really important, not only to grow the hub of Melbourne City and also the game, develop the women’s game as well,” she said.

“You get a lot younger players coming in, they want to be like Kyah Simon, Steph Catley, Williams and that’s very exciting to see we ourselves are getting our names out there and being an inspiration to young girls and it’s pretty exciting when they get excited.”
