England and Reading midfielder on BBC Red Button
If I was playing for Birmingham City I'd be saying 'test the keeper early on' - and that's exactly what they've done.
Lucy Quinn
A couple minutes of madness have cost Manchester City dear.
Firstly Rachel Williams scuffs wide for the away side from Jess Carter's pass, and then Birmingham's Lucy Quinn finds the corner with a lovely curling effort from outside the box.
But it all came because the hosts failed to clear their lines.
Man City 0-0 Birmingham
It's Manchester City who are having most of the territory early on, but Birmingham have started to string a few passes together themselves.
Worth remembering that games between these sides are usually very closely fought...
