Massimiliano Allegri has urged Juventus to "play ugly" after his side dropped two points in Saturday's 1-1 Serie A draw with Venezia.
Juve had won three successive matches in all competitions without conceding ahead their trip to Stadio Pier Luigi Penzo, where they opened the scoring through Alvaro Morata.
However, the Bianconeri wasted a good chance to double their lead through Juan Cuadrado before half-time and were made to pay 10 minutes into the second period.
Former Torino man Mattia Aramu guided a first-time shot past Wojciech Szczesny from range and Juve, who lost Paulo Dybala to an early injury, failed to muster a response.
The visitors finished with an expected goals (xG) return of 2.13 compared to Venezia's 0.54, but Juve were made to pay for a lack of cutting edge in front of goal.
Juve are now six points adrift of fourth-placed Atalanta, who face Hellas Verona on Sunday, and Allegri admitted his side need to improve in certain areas after their latest setback.
"It was a good first half, but then we had a 10- or 15-minute blackout before the Venezia goal," he told DAZN.
"The same thing happened against Salernitana recently – we were lucky then not to concede as they hit the post – so it's something we clearly need to work on.
"We were under pressure, couldn't play the ball to feet anymore, so we should've had patience with one or two balls over the top to the strikers, but we didn't do that.
"We had to attack the space, force them into fouls and more yellow cards, but we threw away two points against a good Venezia side.
"At the start of the second half we were wandering about, giving the ball straight back. Sometimes we don't realise the game is getting 'ugly' and we don't read the moment.
"Once that moment passed, we started playing again and pinned Venezia back into their own half, but the damage was done."
Allegri added: "We have players without a great deal of experience. The whole team was a bit sluggish after the restart.
"We can't seem to realise when it's the time to play pretty and those 10, 15 minutes we ought to play ugly, grit our teeth and push through."
Dybala hobbled off against Malmo in the Champions League on Wednesday and lasted just 12 minutes before being replaced against Venezia.
"We ran a risk, and it went badly," Allegri said. "He went off on Wednesday with a muscular issue; we hoped he was better now, but that was not the case."
Juventus, who had won 15 of their previous 17 league meetings with Venezia, could find themselves nine points off the Champions League places come the end of the weekend.
"We mustn't think about that," the coach said. "We threw away two points today, two points we should've brought home."
