but success depends upon variables and choices he makes, not solely on his ability
Stevan has the talent and the character to make it. An injury aside, nothing can stop him from making it. He's been a hard worker in Partizan, where he was only 16, 17. He's been working even harder after he joined Fiorentina. As he gets experience and he matures even more (he's way too mature for his age), he'll explode one day.
Zarate has more natural talent and is a natural dribbler. But I can easily imagine him become an Adriano one day. He simply isn't a team player. He tried this year, he saw that he can't do it, and now he's back to his selfish ways. He doesn't even look at the others. He's always trying to do everything by himself. Too egoistic. People are fooled by the attractiveness of his dribblings and the way how he goes with his head into the wall, but they ignore that there is absolutely no end product in 99% of the cases and that trying to dribble through 5 opponents rarely works.
Big talent, but little end product.
Someone already said that Zarate will be frustrating to watch if he plays for your team and i agree with that 100%.
