Cristiano Ronaldo was on target but could not prevent Juventus slipping to a first Serie A defeat of the season on Saturday, going down 3-1 to in-form Lazio at the Stadio Olimpico.
The champions started the game strongly and took the lead on 25 minutes. Rodrigo Bentancur slid in a low cross for Ronaldo to slot past goalkeeper Thomas Strakosha.
Lazio equalised in stoppage time at the end of the first half, though, when Luiz Felipe powered Luis Alberto's cross past Wojciech Szczesny to send the two sides in at the break on level terms.
Juventus were reduced to 10 men midway through the second half.
