Nietzche was a structuralist or existensialist?

[Suwalski]

I know he was'nt neither a real structuralist nor existensialist. But í think i've read that post-structuralist Focault([censored]) was inspired by Nietzche. What i don't get is that, as far as im informed, structuralism is sort of anti-democratic due to their believe that society is controled by 'structures' and discourses. In contrary is the existensialism who claims that people are them selfs and able to choose their own direction.

I do realize that Nietzche was very vague or unclear in his pholosphy, yet how can Nietzche be an inspiration to two so different beliefs?

Maybe i stated something wrong, feel free to correct me. i'd appreciate any thought, corrections or explanations! (sorry if any bad spelling).
