Here another viewpoint regarding the academy... and is that the academy can be a a place where to extra-train in some way these players who have 18-19 -20 years...
So we come back to the idea to consider some things as "premium". As should be, a 8* - 9* player, so, if one keeps youngers those can have a benefit. The question now is how, but I guess that adding something like a double XP winning related to a "standard" training affecting different skills, can work.
