eFootball PES 2020
In myClub mode of PES 2019, level 30 represented the baseline level of performance for all players in the game.

In PES 2020, this baseline level will be changed to level 1, so all players perform at their true potential from the moment you sign them.
You will still be able to improve their performance by levelling them beyond the baseline, thereby increasing their stats and Overall Ratings.
Be aware that each player has a different max level, according to his innate potential for growth.
