100 tK a season, i mean 2-3 tk perday (i count 35 free tk of cause)
if you want to play 1-3 season and quit ok, don't care about young player.
even if you have a young player at middle of the season from 18-21 he can improve about 6 * without Power trainning and he will drop to 4* player when he is about 23-24. so 24 T and you have a player, play for you 6 years, it sounds wonderful. And don't talk to me that a 4 * player is useless in normal team, lol
