Retirement

Normal players need to be at least 30 years old and they must have played at least 4 years for your team and 10 hall of fame points. You need to retire them before the contract ends.

Exceptions are star players. They will always go to the hall of fame directly, even if you don't retire them before the contract ends and they don't have enough points and played long enough for your team. Stars must be at least 36 years old to retire them.
