Sometimes it may take a while before the game manages to find an opponent that roughly matches your level.
When it takes too much time to find an opponent, the game will gradually expand the selection pool of users.

If you are not able to find an opponent even after waiting a while, this may indicate that there are not enough players at your level in the stadium that you are playing in. In that case, we recommend that you move on to the next stadium to find more players that are logged in at your level.
