"Losing Gonzalo is important for us but we have to focus on our squad and make sure we are ready for the match," Napoli coach Benitez told a news conference on Saturday.
"Pandev, Callejon or Zapata can all do well. I have faith in them."
Napoli are six points behind second-placed AS Roma, who host Inter Milan later on Saturday, and 15 adrift of leaders Juventus who visit AC Milan on Sunday.
