The 1-0 victory at the Stadio Olimpico puts the Bianconeri one point clear of Udinese despite having a game in hand.
"Tonight everything went our way and it's only right to underline how well Lazio played," said the goalkeeper.
"The Scudetto? Let's keep our feet firmly on the ground. Of course we're happy with tonight's result and the performance, but let's just keep quiet about anything else."
