I've finish my data search about him, here are some images, suggestions and arguments.
Era: It has to be 1953-1959, 1953 was the year when he start to have a real development as a player in C.A.I., that was the year when he score that great goal against England and he play with Rodolfo Micheli, Osvaldo Cruz, Carlos Cecconato y Ricardo Bonelli and when do that great performance against RM.

STA: according to what i find out, he was highly praised for his physical deployment on the field despite being an offensive midfielder, according to my sources he was "tireless" just great, imo 82 material.
AGI: Should be in 85ish since him was a player that usually show electrics moves around the field and imo his current DS value doesn't help him to reflect that.
