The Serie A leaders surrendered a 2-0 lead to draw against the Neroverdi at the Mapei Stadium-Citta del Tricolore.
Danilo and Gonzalo Higuain had put Juventus ahead inside the first twelve minutes but the hosts capitalized on a lapse in concentration in the visiting defense to score three goals in 25 minutes.
Alex Sandro struck to salvage a point for the Bianconeri later on in the game.
Juventus are now winless in their last three Serie A games despite having a healthy advantage to win their ninth Scudetto.
In an interview with Sky Sports Italia after the game, the Italian tactician expressed his disappointment in his side’s display and insists he expects consistency from Juventus.
“A coach expects consistency from his team, it’s something we’ve been lacking both physically and mentally,” said Sarri.
“Any team becomes dangerous if you let them pass it around in our final third.”
“At times, I get the feeling this team has enormous potential.”
“At other times, it leaves you perplexed, as it allows the opponents to enter the box far too easily.”
“We need to find the right balance and that is not easy."
