not debating if he is good at training players. since S8 you gave 3 examples of rookies he bought after a season with some other team. he trained nothing he drafted with that team. that is all i am saying. i am sure he knows how to train awesome players...homegrown means for most draftees...and 3 players is not a team...its 3 playrs..since s8....the rest/most of his players, were trained by whom? and then he bought them, already traind.
Draft is a matter of luck,though.You got to be very lucky to draft one guy that is so good for skills/potential/age that are capable to reach chertain levels
He bought young players and trained them pretty well,Mamba is a good trainer and manager
As i have stated in my original post here,is true that Chinese managers trained their players as Dyonisus wants so that he can buy them,and Dyonisis made borderline TPA transfers finding noobs all over the world that overpayed his players,but this doesn't change the fact that Mamba is a pretty good manager
