Yea sure, but it costs u way more token n u never know if the player u might need will appear as a nordgen on the list later on, and if the new nordgen doest end in 4 o 9 u didn't have any benefit, besides spending more token, if u buy a nordgen now, he next season is still better than every other player in the game (besides other nordgens), so unless u don't face an oponent who has a squad full of nordgens, u still better of with one u buy now
And thinking about the greens o reds cause of power training is not a reason not to do, cause u would spent many more on a youth player...., nd if u able to talk about buying nordgens whenever they appear i think token buyer, so they shouldn't worry about greens n reds anyway.
