Go to a soccer match

You decide to go to a soccer match at your old association. Once you enter the facility there are some matches going on. You pick one of the matches and start to watch the game.

You then make a wish. " I wish every person would leave the facility. Except for the players in this match."

To your surprise it works and all the supporters trainers and staff start to walk. Once they left it is only you there with the match still going on.
