Spluttering Juventus failed to win for a fifth consecutive game when they were held to a 1-1 draw by Fiorentina in Serie A.
Both sides moved to 15 points, one below joint-leaders Sampdoria and Inter Milan.
Juan Manuel Vargas put visitors Fiorentina ahead on five minutes when he latched onto Stevan Jovetic's clever pass and prodded home at the near post.
Amauri then scored his first goal since February to level for Juve after Vincenzo Iaquinta had squared the ball for his strike partner following Christian Poulsen's incisive pass.
Brazil-born Amauri, hoping to force his way into Italy's World Cup plans once an Italian passport arrives, could not miss the 19th-minute tap-in but still celebrated wildly after his long drought.
Former Fiorentina midfielder Felipe Melo headed just over in the second half but Ciro Ferrara's side lacked fluency with playmaker Diego again struggling and Mohamed Sissoko feeling his way back after seven months out with a broken foot.
Fiorentina, who featured former Juve players Cristiano Zanetti, Marco Marchionni and Adrian Mutu, had a deflected Vargas goal disallowed for a push.
