Leadership examples abound in the FIFA Women's World Cup (to which I am currently addicted as the Strine/Nu Zild time frames are spot on for nightly peak viewing).
I'm loving watching the way coaches interact with players and how players interact with each other - clear leaders emerge, or don't.
Seems to me that on some teams there are some natural leaders, who the women follow.
In one game I watched a young goalkeeper explaining to her much older, more experienced team mates, some tactical points. And they listened!
Teams without natural leaders don't tend to stick around for long in these kinds of competitions.
