Not agree with some opinions. I really don't know why people see the "valoration" of the player and thinks that this is the 1st important. ¿?
in my experience I bougth some idiots that do nothing and have 7 as a valoration during... all matches.
Don't see the valorations and just see how he works, and how effective is in his position, or for example if it's a ST with low valoration try to put this player only in the 2nd half. Every player have a mode to work, if he work. If don't work, and you never see his name in the matches doing something for the team, simply, sell this guy.
