Leonardo has asked his players to react when Inter meet Napoli in the Coppa Italia quarter-final tomorrow night.
Inter lost 3-1 to Udinese on Sunday bringing to an end Leonardo's perfect record in charge of the club.
He had won his first five games in succession since taking over from Rafa Benitez in December.
"Napoli have done well recently and I expect a similar team to the one that we faced at the beginning of January," Leonardo said.
"The atmosphere at the San Paolo will be beautiful and I expect an important game.
"Being consistent is obligatory for teams that want to win. There is motivation because we are playing against a team in fine health."
Asked about reports linking Inter with Luis Fabiano, he said: "I like him a lot even if with respect to two years ago he has had a lot of injuries and renewed his contract with Sevilla.
"Today the situation is different. He is a centre-forward, an important reference point.
"There is not a real need for a striker because if we have everyone available, we are in place. But having an extra alternative is important when there are problems."
