Took a look at the Luzern squad list, only one name I've ever heard - Max Meyer who was supposed to be the bright young hope of German football a few years back, then signed a massive contract at Palace when his contract ran out at Schalke.
Hardly did anything for them over three seasons and ended up kicking around Danish, Turkish and now Swiss football for the last few years. Seems to be doing pretty well for them now though.
