Totti came off the bench against Juve to score in the crucial win.
"This gives me a feeling that Roma can challenge for the Scudetto. But keeping our feet on the ground, we still must work hard to get to those levels," said Totti.
"From Siena onwards we have changed our season, we changed the track and found the right mindset even though we lost those three games in a row.
"Now let's go step by step, but you will see that we can go far. We won in Turin, and with a goal scored by me, everything goes well but now we must be sure not to suffer from vertigo by our high ranking!
"Claudio Ranieri is a Roman doc, a great coach, a man who knows the locker room. He's charismatic and has clear ideas."
