The Sports Director: he is the one that will scout the market for the type of players you want and depending on the level of skill the employee has, will find better or worse players in more or less time.
Searching For Players
Once you have signed your sports director and you know what your team is lacking you can give your sports director the guidelines and parameters to find the players you need.
Depending on how good the employee is, the players will be found in less or more time and will fit best your parameters. This game logic makes the game feel more real as in the real world sports directors take time to find players.
