Thanks for the answer man.

What about intensity coach (x134) you get at second lvl from Boost lab event?

You got to spend the amount of resources in academy enough to coach young player so he has full 7 stars at the end of training? That would mean the player has to have full 130% of skill at the end of training, and only then you can get the coach (x134) from Boost lab event, or am I missing something else there?
