Juventus coach Maurizio Sarri urged calm after their shock 3-1 defeat by Lazio.
Juve went into the game the only team remaining in Europe's top five leagues who were unbeaten. But fell to Lazio as Luiz Felipe, Sergej Milinkovic-Savic and Felipe Caicedo struck for the hosts - all after Cristiano Ronaldo had put Juve ahead.
Sarri said afterwards, "I thought we had a good first half, doing very, very well, but unfortunately allowed that goal right on the stroke of half-time.
“The second half was dominated by incidents, most of which went against us, but when it was 11 against 11, we did very well."
But he also said: “We didn't respect our duties, because players were in the wrong position, it was a distraction and you pay for that. We had decided before the game on certain positions and we didn't cover them.
“I didn't see many mistakes in the first half, we passed it around well and had the chance to make it 2-0 with Cristiano's header. We were perhaps a little slow to react on the corner, which sparked their goal.
“In the second half, when the game seemed to be in a more balanced state, the red card changed everything. We lost the match, but to be honest, I saw improvements in my team."
