Lazio President Claudio Lotito insists that his players must roll up their sleeves after back-to-back defeats in Serie A.
The Biancocelesti were knocked off the top in midweek, but still lie second in Serie A ahead of Sunday's clash with Napoli.
Interviewed on Radio Sei, Lotito said: "We must make treasure out of these two defeats and always do better.
"It's the moment to roll up our sleeves and to remain united. We need humility, spirit of sacrifice, knowing that every game presents great difficulties.
"I am absolutely not worried. The defeats against Roma and Cesena were very different.
"In the derby we went out on the pitch very tense and then there were other factors that were brought to bear, while on Wednesday we also paid for the many absences owed to rotation.
"It would have been different with full strength team," he concluded.
