Keeping players longer in Manager mode
Before you start Manager mode with a team, edit the age of the players so they play longer for your team. For example, with Liverpool’s Steven Gerrard (age 28) might play for five years. However, Steven Gerrard (age 14) will play for at least twenty more years.
