How about Languages. When I pre-sign a player from a foreign country, especially a youngster from Brazil or something who is due to transfer in 18 months or so, it would be nice for them to start learning the native language of his destination club off the bat, so he is already at least [basic] when he arrives. Maybe be able to have a dialogue with them before the signing, so maybe ask them to start learning...?
As far as I know, young players sometimes start learning foreign languages even before coming to the new club. For example, once I bought a very perspective Brazilian player. He was only 16 years old. Just a few days before the transfer I looked at his profile, and I was really surprised, because he knew not only Portuguese but Russian as well. It is already in the game.
Sorry for my English, by the way, because it's not my native language.
