Btw, players like you said seems a bit overrated, 90 in Attack for Alex Sandro, like i've said, it's a bit hard to convert PES>FM
Also, you said that Fifa makes random stats, but FM too. You could check with the Fm data editor, there's many stats with "0", excepted one or two sometimes, especially for less known players.
But they've got a system to remedy to that issue: with the current and potential ability, it "converts" stats with 0 in the editor to a standard set of attributes...
Even for Height and Weight. Some unknown players will have a random height and weight.
Like i've said, FM isn't really the best solution. But not the best...
Fifa have the same system, based on height/weight/position/age/current overall and potential overall... But also the league level in which the player's play.
They've got Height/weight standards for players they don't know about, based on position 185cm 80kg for GK, 175/70 for winger etc., but they don't gives random height weight like in Football Manager.
In fact, EA database is less complete, but less randomized than FM.
Also, FM have many overrated players in lower league, 16 years old a bit known wonderkinds from lower league with exceptionnal stats. It doesn't match with PES standards.
A Fifa>PES converter should be a better option.
But Fifa also have some issues in their rating system: aging players will have their speed/movements atttributes radically increased with their age, same for stamina if a player is on the bench for a little while. They increase/decrease a bit too much their players in some area, so if we convert a player, we should take his attributes from the start of the league, and makes good combinations.
Or to create a global rating system with all informations we can have about a player by ourselves, but it's hard.
Sorry for my english too btw
