England U21 international Palmer made 15 appearances and scored one goal during her United career, and had most recently been on loan at FA Women’s Championship club Sheffield United for the 2019/20 season before being recalled in January.
Everyone at the club would like to thank Aimee and wish her the best of luck for the future.
United Women head coach Casey Stoney said:
“Aimee has been with us from the start of this journey and will be forever be a part of Manchester United Women’s history makers. I have seen her grow as a player and person both on and off the pitch, and I would like to thank her for her efforts over the last couple of years and wish her the best of luck going forward.
