It's funny isn't it, not once when watching women's skiing or athletics do I think "Buh-but itz not lyke da menz one".
Problem with football is it is played on an absolutely massive pitch so levels and difference in those levels is off the charts.
Skiing and Athletics bar marathons last a fraction of the time. You are talking less than 5 minutes in most cases. Football is 90 minutes of 100% flat out. It is very unique in that respect and has to be one of the most physically demanding sports out there.
If they made the pitches smaller the women's game would be far more entertaining.
