Williams becomes the fifth Australian at the Women's Super League giants after Caitlin Foord and Steph Catley joined Aussie coaches Joe Montemurro and Aaron D'Antino.

Williams signed a one-year deal with the Gunners, with the option to renew for a second season.

The Australian take over in North London caps off a strong season for Williams personally, where she set a new W-League record for longest without conceding en route to winning the 2020 W-League championship with Melbourne City.

Williams' greatest challenge over the past few seasons in the NWSL has been cementing a starting place, with the Matildas' shot-stopper a perennial fixture in the Australian lineup but, at least recently, rarely played overseas.

Working her way into the fray at Arsenal will likely be an even greater challenge, given the Gunners' wealth of options and current number one, Austrian Manuela Zinsberger.

Williams does, however, have the massive and ever-growing Australian contingent at the club to give her a natural advantage.

A rarety for Australian football at the elite level, but one that appears to be changing fast.
