Money, it becomes a huge problem for further levels, either money we gained must increased or players' value must decrease. This is an unbalanced situation.

Moreover, "Youth Academy" is totally useless. I pick two players one is 2 star (free one), other one is 4 star (average 20 token). They both doesn't fit to my team. Youth system must change. We are waiting for 12 days to get a player for just selling.
