Tarik(Internacional) - Becomes a very good Deep-Lying Playmaker Jonas Svensson(Rosenborg) - Advanced Playmaker Leonel Galeano(Independiente) - Becomes top DC
Lisandro Lopez(Arsenal Sarandi) - Another top DC prospect Romuald Lacazette(PSG) - Tiote replacement?? Marco Verratti(Pescara) - Top class Playmaker Zezinho(Bahia) - Inside Forward/Winger Carlos Fierro(Chivas) - Poacher Yannis Tafer(Lyon) - Poacher
