Not sure is this already suggested, but with season 19, some of players bought as young player getting to be retired.

To remain memory of great performance they did, I propose to have Hall of Fame where you can see best top 10/100 retired players classified per club, national team, continent, overall, with different categories as best AVQ, best scorer, best assistant, best rating etc. 

Maybe even consider that best retired players gives very small increase of morale and/or club popularity.

That would be a nice addition, I also suggested it in the past. But I think it should be just for fun, with no effect on the morale or popularity.

If any, the retired players could be available as staff for the team, but they shouldn't be any different from the other coaches and scouts 

A hall of fame will be nice
