they do it for quite a lot of players, epecially young ones and almost exclusively for ones with a non-fixed PA eg -8 -10 -4 etc. The zeroed stats are set to be completely random on each game. I guess if they have decided hes a potential wonderkid but havent worked out if he will be a targetman or a dirty player or very composed etc then they just leave it at 0
players with a fixed PA like 186 usually have numbered stats.
i have been trying to sign him since the begining of my game, found him ages ago but never had the wages to offer anyone a new deal, he eventually signed for a free to a semi small club, cant remember, was desperately trying to get him though, once again i had no wages to offer him!
pretty bleak about it, i rate him highly
he is quite similar to lukaku who seems to be different every game because he doesn't have fixed p.a for attributes but i have stumbled across him before and he didnt seem that promising
