A bit more in-depth:
Rapid's keeper is Helge Payer. He is really good, despite his young age. Can make a difference.
Their defence is shaky...there are some new players..Radek Bejbl is prominent, but old, Valachovic is another Czech. Labant is injured, the rest is not worth to be mentioned.
In midfield there are two strong wings. Ivanschitz is Austria's biggest talent, very skilled, Hofmann the Austrian player of the year. In the center Korsos and Hlinka do the dirty jobs.
Their strikeforce is Kincl, Lawaree and Akagündüz. Kincl is strong and dangerous, but slow. Aka is quick and mobile.
Rapid is Austrian champion - but by no means the best squad in the country. They won the title because Austria and GAK focused on Europe and hadn't enough power in last season's finish.
