Im having a bit of a problem- I know that you give them a couple of games when they are 17-19, but I feel like if I screwed up somewhere. I started giving Carlos Fierro limited gametime around 21 yrs old (Stupid french rules regarding non EU's) , and now he is one of my main strikers. But he is only listed at 3 star potential, when he was listed at 3 1/2 when i first got him. He is 22 right now, and is at 2 and 1/2 stars. Should i be worried? Can he pass 3 star potential if I keep playing him in every game?
