"It's a very exciting day for us," Cushing told the club's official website. "We want to play a major role in the WSL and a major role in women's football.
"We're building a very exciting project, we're taking it very seriously and we're very much looking forward to getting started.
"It's a new league and a new adventure for us, but our aim is to be as competitive as we can. We've got a core bunch of players, but we need to build a bigger squad and develop the culture and environment of the team - that's very important to us, but we're looking forward to the challenge."
The new season gets underway in March 2014.
