Juventus suffered their first Serie A loss of the season as their 10 men were humbled at home by Fiorentina.

 

Juve's ex-Chelsea midfielder Juan Cuadrado was sent off for a lunge on Gaetano Castrovilli in the 18th minute.

 

Fiorentina were already ahead by that stage after Dusan Vlahovic lifted a composed finish over Wojciech Szczesny.

 

Cristiano Ronaldo had a header chalked off for offside for Juventus before an Alex Sandro own goal and a Martin Caceres effort sealed a famous victory.

 

Defeat capped a frustrating day for Juve, who had already lost three points and dropped to fourth in Serie A, seven points off the top, after their walkover victory over Napoli in October was rescinded.
