Soccer try outs, whats expected?

I'm trying out for a couple select teams and then in a couple months my highschool soccer team. I'v played for almost nine years know and I'm purely a goalie. I've never played anywhere else and haven't been subed in or for any kind injury or anything I just always am in goal. I really don't have that much footwork because I've never had the use for it. I was just wondering what coaches look for in a goalie at tryouts? Will I not get picked just because of my lack of footwork? What makes someone stand out in try outs? Any advice would be greatly helpfull. Please and thankyou!
