The reigning Serie A champions kept their slim chances of retaining their title alive on Wednesday after recording a 3-1 come-from-behind victory over relegation-threatened Parma.
Juventus' task got off to the worst possible start in the 25th-minute when Gaston Brugman opened the scoring from a free-kick, with Ronaldo guilty of ducking under the Uruguayan midfielder's effort.
However, a brace from Juan Cuadrado, who also recorded an assist for Matthijs de Ligt's goal on the night, ensured that the Bianconeri came away with all three points.
Following the match, Juve boss Pirlo played down his star man's error for Parma's goal, although he did admit that he would consider removing the five-time Ballon d'Or winner from the wall in future.
