Martin Caceres was on target against his former club as Fiorentina inflicted a shock 3-0 defeat on reigning champions Juventus on Tuesday.
Ten-man Juventus' unbeaten start to the Serie A season was ended by Fiorentina as they suffered a humbling 3-0 loss at the Allianz Stadium.
The champions had gone 12 games without a loss in the top flight under Andrea Pirlo prior to Tuesday's setback, coming on the day they discovered their 3-0 forfeit win over Napoli in October has been revoked following their opponents' successful appeal.
Dusan Vlahovic scored early on for Fiorentina and Juve then lost Juan Cuadrado with 18 minutes played, the referee upgrading the yellow card he initially showed to a red following a VAR check.
