Attacking midfielder Nairn 28, returns to Victory for the fourth time, while it will be the first time in Australia for 24-year-old Weatherholt.

Both players are coming off solid campaign in the NWSL with Pride which finished the season in seventh.

Coach Jeff Hopkins was delighted to land the two US international players for the 2018/19 campaign.

"Christine was a key target for me because, similar to Tash Dowie, she has been here before and knows what we're about," Hopkins told Victory's website.

"She's a leader and sets a really good example for the rest of the squad with her professionalism.

"Dani is a talented midfielder not only has great defensive qualities, but also gets forward to support attacks.

"She's a great team player and very influential both on and off the field.

"I'm really happy with how the squad is coming together and obviously it is pleasing to lock in two quality international players who bring a lot to the group."
