Zanetti made his comeback against Livorno last week.
"Coming off this serious injury, my first sensations in the Livorno game were fantastic," he told Sky Sport Italia. "This was the first step I had to take.
"Right now the team is doing very well and I don't believe I have to begin as a starter. I just came back.
"I'll get into a condition that will allow me to give the team a hand, just as I always do.
"The most important thing we can do as a group is to be competitive and we all want to play our part."
