Serena won, woo!

For some reason I was comparing Aussie rules footballers (and probably American footballers too) with tennis players. I've never heard an interview where a tennis player sounded stupid - sometimes perhaps they didn't quite understand English properly, but they did their best with a foreign language and didn't sound dumb. But footballers so often sound utterly dumb.
I don't know why I made that comparison. I mean, could two sports be any more different, than football and tennis? Well, they probably could. But it's a figure of speech, which means it doesn't have to be correct as such!
