No way, my player's stats are mine! If somebody wants to see my player stats, then he should upgrade his scout and scout my players, only then he will be able to see my weak/strong spots.
I don't know a single NT manager that uses NT to see his oponent's weak spots, he only uses the data he can get to win matches with the NT, why should you get that info for free?
Nothing is free, and that includes my player's data.
I guess that a NT manager should be allowed to see complete data for all players of the country of the NT he manages.
For example the Italian U21 manager should be allowed to see all data of italian U21 players only. The italian NT manager the whole group of italian players and so on.
Anyway I think that NT teams should be something that should imply great cooperation and partecipation for the whole community otherwise is meaningless.
If any NT manager wants my player's data for NT use, he will have them inmediately, if NT manager can't get something as simple as player's data easily, that player doesn't fit for NT,
without communication, any NT process is destined to fail badly.
I won't tell you how argentinan NTs are managed, but i will tell you that NT, U21 and all the scouting staff can see the data of every single player that played for NT at least once (that includes around 10 players that belongs to me), and if any manager wants my player's data, he will have them inmediately.
I could also tell you that they can also see my foreign player's data who plays for NT.
As you can see, many rivals can know my stronger players. Now, why would NT manager need my subs and weaker player's data just because? He doesn't need it at all....!
