Como secured a narrow 1-0 victory over Venezia in Serie A on Sunday, with a penalty from Da Cunha proving the difference at the Stadio Giuseppe Sinigaglia.
The spot-kick, converted confidently by the Brazilian midfielder, keeps Cesc Fabregas' side in strong form as they continue their campaign in the Italian top flight.
Fabregas, the former Spain and Barcelona midfielder now in charge of Como, will be pleased with another three points that maintain his team's positive momentum in the league standings.
Venezia, despite the defeat, remained organized throughout but lacked the cutting edge to trouble the Como goalkeeper seriously.
The result leaves Como with a valuable home win as they look to establish themselves in the division under their high-profile manager.
