If you never get yellow card and manage to thrash the opponent 5-0 and above. You get 1 green 1 red and 3 blue. Now I am stockpile with lotsa blue but I think July is the wholesaler with 800 morale packs
I've got 524 to be exact. Friendlies are worth it if you don't mind getting injuries and not healing some players immediately, I mainly play with reserve/sub players. I've played 8 so far this season.
