"I have lads in great shape, so it makes sense we would be very attacking, as we tried to raise the tempo of the game," said Ranieri after fielding a trident attack.
With this result, the Bianconeri close to within a point of Roma in second place, although they remain 12 adrift of leaders Inter.
"In terms of spirit, desire and everyone helping each other out, we played a great game," added the Juve boss.
Roma coach Luciano Spalletti was unhappy with his team's flat performance and said: "In the first half we didn't do enough. We were too rusty in interpreting situations and creating play. We went better after the break, but clearly still less than we could have done.
"We cannot allow this kind of an advantage to talented players like those at Juve. Maybe the players were a little distracted because they looked at the calendar and know they have only one chance in the Champions League, whereas in Serie A there is time to recover."
