New player, everything i must know - training, formation, tactic!!! For dummys(me)

[H0lyBoy]

Ok, i read a lot on forum, but its still unclear if for example i can use PSG*5 for an AMC/AML/AMR, i read also about The clean drills so now i have a better ideea about training!
I wanted to create a place where we have ideea for New player...
Also i read this one :http://https://forum.topeleven.com/t...anagement.html but still its unclear... Which player should i keep for next seasson, my curent rank its first în The league and my clubs looks like this now...
Should i Power train now my 19 years old AMC both of them or should i keep the rest packs for next seasson? Until what eating should i train them... If i have to!
