Today I was waiting for 1 good player of the academy... and I recive a 2 stars MR, and 3 stars AMC, well is 54quality so is near 4 stars... but the problem is that I don't use this positions....-.-*

in my case, I sell every season the player of 2 stars for $$$$$$$
and.. the better young that I had, is a DC that wins 170 with the 30% training hard, and 110 with the training 20%... but if I remember well, this player costs 24 token, no 18...
and thinking now I had a DR, ... really I have to say that I had good luck with they, usually do a good work, and trains very fast... perfectly, if I waste all the 100% condition and the 4 free green boosters of everyday...can have 8-10 training points easy per day... so, players "made in home" works very well for the boss, in my case... cos I am a very serious boss and they know it^^ (^-^)
about to see players like this in the market, yeah, posible... you say that, you sell the free young player, no? so, be sure, that other teams that have 3-4 levels more than you, do the same with his 2 young star players... and they see 2 stars but you see 5.

So, yeah, of course, you can have the same of your academy, with 5 stars, and 8 stars at the end of next season if you have one.
the problem is now.... that you don't wanna waste tokens, and these players, are who everybody is looking for... and you can be like me... in the market... paying. 32, 33, 34, 35 tokens... and when you put next token, the other player do the same... click-click, click-click... (-_-)''''''' 42,43,50... or 70 tokens will cost if you and the other guy don't stop.... I had this situation.. and thats why every season I pay 150 tokens for 3 players of 6 stars xDDD
And that's my experience (^.^)'
