He played in central defence and he formed a famous partnership with Héctor Cúper in his time at Ferro Carril Oeste.

His nickname was Burro (Donkey), he was a famously combative player and a great header of the ball.

He was also very good at taking free kicks and he scored 78 goals in his career (very impressive for a defender).

Roccia played for the Argentina national football team in 1975 under the managership of César Luis Menotti.

In 1981, he helped goalkeeper Carlos Barisio set an Argentine record of 1,075 minutes without conceding a goal.
