Juventus saw their lead at the top of the table reduced to nine points, but the statistics show an alarming problem in defence.
The Bianconeri were held 3-3 by Parma thanks to a stoppage-time Gervinho strike, despite having been 3-1 up.
Only one other Serie A side had avoided defeat at the Allianz Juventus Stadium this season and that was Genoa, 1-1 on October 20.
Max Allegri’s men have conceded six goals in their last two competitive games, having been beaten 3-0 by Atalanta in the Coppa Italia quarter-final midweek.
Before that, Juve had let in only six goals in the previous 14 matches put together.
Clean sheets are also at a premium, with just one in the last five Serie A games, a 3-0 victory over bottom of the table Chievo, conceding seven goals.
