The result means that Viola are now seven points off a Champions League spot after seven games.
"It is an important result and we take the point, even if Lazio did more and deserved something more," the 39-year-old told Sky Sport Italia.
"We tried to take the initiative, but we weren't sharp enough tonight. The result is positive, because last season we wouldn't even have managed that with this performance.
"The break comes at the right time, as we can get some players back from injury and rest others who haven't had the chance. It's no coincidence we lacked sharpness this evening."
