Following a four-season absence from the WSL, Birmingham are back, having won Women’s Super League 2 last season.
The Blues edged a thrilling title fight with Palace and Charlton, clinching the trophy on goal difference by winning at The Valley on final day.
They showed quality going forward and in defence, scoring the second-most goals and conceding the second-fewest.
They also finished with the league’s best goal difference, while striker Lily Crosthwaite picked up her award for WSL 2 player of the year last week.
Among six new signings, head coach Amy Merricks has recruited experienced centre-back Millie Turner, who made 145 WSL appearances in eight seasons at Manchester United, has two England caps and is the new Blues captain.
She will play alongside talented 23-year-old Neve Herron, who was named in the WSL 2 Team of the Year.
“There’s going to be challenges, there’s going to be moments, highs and lows, but come that first game of the season, we’re going to be ready,” Herron told BBC Sport.
