I am sure that:
Man City will surprise a lot of people. No CL and it would be very unfortunate to suffer as badly with injuries as last season, so their squad won't be stretched as much. Best attack in the WSL, all fit and having had a proper pre-season.
And the other certainty for me is that Man U will fall away.
Beyond that... The most I'm hoping for is that it is a realistic three-way battle until the end. But I suspect Chelsea will do it again. Sorry, fellow Arsenal fans. We are nearly there, but not quite.
