Second-placed Napoli's hopes of another victory to keep on the tail of leaders AC Milan have been helped by Sunday's visitors Udiniese being hit by injuries up front.
Top forward Antonio Di Natale is doubtful with an ankle problem and strike partner Alexis Sanchez is also not fully fit, so Bernardo Corradi could come into the side.
"Coach Massimiliano Allegri told him he could spend the night at the hospital if he wanted but instead he wanted to train," Milan chief executive Adriano Galliani told Sky.
Inter Milan president Massimo Moratti, whose third-placed side visit lowly Parma on Saturday, has reacted calmly to the holders' Champions League quarter-final exit and expects his team to give their all in an unlikely pursuit of a sixth straight scudetto.
"Today I would like to thank my team, all the players from recent years and the current side who have brought so much joy to all Inter fans, myself included. We are, and always will be, proud of their achievements," he said in a statement.
"I'm sure the team will dig deep and find the strength and quality we know they are capable of, so that we can achieve the targets we are aiming for this season too. And I'm sure, with the fans' support, the coach and team will bring us more joy."
"The feeling in the dressing room is good. We still have six matches and we are convinced we can save ourselves. I don't think the game with Inter is the most difficult, they are all tough," he told reporters.
