Depends. When I want to play a real game I dont, but when I get bored of it and just want to create a Juventus dream team then I do.
Anyways, some young players have -2 potential set in the pre-game database. What it means is when you start a game their potential might be anything from 160 to 200. Let's say Oliveira's potential is 190 in one game. If you start another game (loading the database and all that) his potential might be 167 in it.
Anyways, I have this team now (Juventus of course )
LB Dede (Zauri)
CB Metzelder (Tudor)
CB Lucio (Legrotagglie, Mexes)
RB Zambrotta (Yobo) - yes, thats right, I'm playing Zambrotta as a right back
ML Nedved (Rothen, Robben)
MC Aimar (Maresca, Deco)
MC Pirlo (Appiah, Redondo)
MR Camoranesi (Miccoli)
and what else i wish could happen is that when you finally become the greatest team in the world you can buy entire teams with all the money you make. is there a limit to the number of players you can own or have in your squad?
The best defender is Ferri he starts in the first season with tackling around 15 and marking and strength 14.
But after two seasons he has 5 twenties including marking tackling and strength...
BTW he is 19.
