DESCRIPTION / EXPLANATION:
This guy is simply incredible and I haven't doubts that he'll play in a big team in Europe. His sense of positioning and mostly his tackling is just impressive, he remembers me first Milito's step taking into account his insane recoverings of balls, and he's really similar to Otamendi. Also, he has some ability with the ball in his feet to be a "hard" defender...owner of a great mentality being really young, he scored two important goals when Independiente was champion (one at final vs Goias). May be his worst aspect is his teamwork, he hasn't a good understanding with his teammates in defence but now with Milito near him is doing a better job. I didn't compare with other player to make this set but really he deserves that level of defence, he's probably after Milito and Schiavi the best defender in AFA league, and most impressive is his consistency...almost all matches he plays at the same level. Also he has a good experience to have only 21 years and he won an international cup til now. If you have the opportunity, follow this guy cause is a real serious thing and he had offers from Inter and Barsa to take porcentage of his transfer but he wants to stay more in Independiente to learn from Milito's knowledge. His response was getting better along matches, cause at the beginning of his young career was his worst aspect, but he improved a lot and he's owner of a great timing.
