I get to watch a lot of women's football because it's televised a good deal here in France. The difference in standards across teams in the same league is big enough but taken across the world, even more so.
I follow Leicester City Women (when they're on the FA Player, or club TV) and last season they walked away with the league and were promoted to the WSL. They got several new players in over the summer but they are struggling, stuck firmly to the bottom without a point. The difference in standard in the WSL is obvious to see. Hopefully, in time, those gaps will close.
On a general note, I do enjoy watching the women's game. It's a different game and that, for me, was the key to enjoying it - appreciating that it is a different game. Tactics and skills are there, the physicality is different.
I watched the France v Wales match last night, and with Wales 1-0 down and maybe 10 minutes to go, a Welsh player struck a volley sweet as you like, difficult enough given the way the ball came at her, but it was on-target and had some wellie..... only to be pushed wide by a top drawer save. Excellent stuff.
If you ever have the chance to watch Wendie Renard (CB for France and OL) then do so, she just oozes class.
