West Ham have signed Canada defender Shelina Zadorsky from fellow Women's Super League side Tottenham on a one-year deal.
The 31-year-old rejoins Rehanne Skinner's Hammers after spending six months on loan there last season, making 10 appearances.
Zadorsky, who also worked under Skinner at Spurs, played 56 times for Tottenham after signing from Orlando Pride in 2020.
"I'm delighted to be back at West Ham United on a permanent basis," Zadorsky told the club website.
"Rehanne and I have built a great relationship over the years and I think she knows how to get the best out of me. I always demand high standards of myself and I really want to be that rock at the back for the team."
Zadorsky, who played at her third Olympic Games in Paris this summer, was part of the Canada squad that won gold in Tokyo in 2021 and bronze at Rio 2016.
