PRO EVOLUTION SOCCER 2019

If you pre-ordered the game then you will unlock this trophy easily, as one of the many players you get is a Black Ball.

- Legend
- If you had two 90 rated player level 30 from the previous year
- Partner Agent

If you didn't then I can only say trying to save GP or coins to play the agents that will be released throughout the game. A new feature to PES this year is Featured Players which is higher rated versions of players in the game. I myself through the agent only unlocked gold balls but you could easily sign one black ball and have a fantastic player.
