I stopped when I saw Igor had posted. I
can say that Zurich fans are pretty confident of seeing off Luzern and are expecting to meet Basel in the final, as you can imagine. I'd be cautious of Will 1900 though as they managed to beat what appears to be a decent Young Boys side in the last round.
Here's the Wil 1900 site translated into english: edit: no it aint as the link won't work. When you go to their site click 'automatically translate this page' or whatever it is and google will do it. It's certainly easier to read than German anyway (unless you speak German of course.)
I've noticed Swiss club sites aren't the most in depth though. They don't seem to like talking about their upcoming matches much as far as I can see.
