"At some point I always wanted to try playing overseas and experience different styles of play," said Lavelle.
"The FA Women's Super League continues to grow and get stronger every year and this was an exciting opportunity for me to take and join up with some great players.

"I am a homebody and it is a big move for me coming to Manchester, so to have somebody who I consider to be one of my best friends going over as well makes everything much easier."
