To make this easier on yourself, bump up game time to at least 3 minutes in the Settings Menu. I personally did 5 minutes. Also make sure to set AI to Easy so they don't crowd you while you're spamming passes.
What I did was took the ball to one of the corners near my goal and spammed A to pass and RB to change to the nearest player. I'm not exactly sure what constitutes a successful pass as this game has very strange mechanics, but doing this it unlocked for me.
