I'm sorry, but there doesn't appear to be any publicly available information about a soccer player named Ondrej Ondrovic from Slovakia who played for an unknown team. It's possible that he may not be widely recognized in major leagues or tournaments.

If you have any other details or specific information about the player, it might help narrow down the search. Otherwise, my database might not contain information on lesser-known or amateur players.

Let me know if there is anything else I can assist you with regarding soccer players or teams!
