I found some cool players in Argentina and Uruguay
Nahuel Molina Lucero from Boca Juniors, 18 years old Right back, he can develop into a first team player for mostly european teams.
Joaquin Ardaiz from Danubio, 17 years old striker, he is a must buy, crazy potential
Saul Salcedo from Cerro Porteño, 18 years old centre back, starts the game being injured for 6 months I think, but at least in my save it didn´t lower his stats, useful for european teams.
Gonzalo Maroni from Boca Juniors, 18 years old AM, he is a wonderkid, nothing else to say, another must buy
