True. I did some digging into this subject a few years ago when Joey Barton made some comments about it (and was widely called a sexist).
My take:
- Goals should be slightly smaller. Purely based on size, average reach etc. Not too much smaller, but enough that a keeper has a decent chance of saving a shot that is slowly looping top corner bound from 30 yards.
- Pitches should be the same size. I disagree with the argument that pitches should be smaller because women are smaller than men. I think it's too the advantage of the women's game. Men's pitches are arguably too small now, given the increased athleticism of players over the years, general increased height of population, plus the offside rule, a team can park the bus and be difficult to break down, and this is amplified on a small pitch. And you cant make men's pitches bigger given the stadiums they are already in. For the women's game, having pitches which are essentially/comparatively bigger means more open games, more goals.
- Balls should be smaller. This is the seemingly controversial one, but there are some studies that show that the average female footballer is considerably taller than the average female, whereas in men's football, the difference between average height of players to general male population is negligible. The theory is, given a correlation between height and foot size, many shorter women have feet that are too small to manipulate a football in the same way. So, by having a slightly smaller ball, more women would have the opportunity to play at the top level, whereas currently a large % are blocked simply by their size. Part of why the mens game is so great is that virtually every size and build can play and make it to the top level, whereas in the women's game, it's much more restrictive currently.
