Goalkeeper Pauline Peyraud-Magnin will leave Arsenal Women when her contract expires this summer.
The 28-year-old France international made 26 appearances in all competitions after joining from Lyon in 2018.
Peyraud-Magnin helped the north London club win the Women's Super League title in 2018-19.
"Everyone at Arsenal would like to thank Pauline for her contribution to the team’s success," said a statement on the club website.
Arsenal finished the 2019-20 campaign third in the WSL table after the season was curtailed by the coronavirus pandemic and the final standings were decided on a points-per-game ratio.
