Question about retirement

[khris]

players can be retired between 31 to 34 of age.

edited1:. and they announce retirement when you are not waiting for it, it doesn't matter the years of contract or the coffee that was drinking with you.

edited 2: players in this game have between 18-34 age. They announce retirement when season starts, so, that's why you can not sell him his last season. That's why I say that announce retirement when u don't expect, and thats why for me a player is expired when have 30 years and I sell this.
