Daniele De Rossi says AS Roma have been transformed under coach Rudi Garcia.
Roma defeated Bologna 1-0 on Saturday.
De Rossi said: "I don't know if Juventus will start to drop points now or if it'll be a spectacular end to the season, but we just need to win and hope they and Napoli drop points.
"You can tell it's a good season from lots of little things. In the summer with those who arrived, winning the derby in Week 4, the fundamental victory in Udine, the run of results after our defeat in Turin.
"It is already impressive that we are so close to a team that was constructed to destroy all competition in the League."
