Inter President Massimo Moratti thought Leonardo's debut went very well after a 3-1 victory at home to Napoli.
The highly regarded Brazilian tactician took charge of his first game since replacing Rafa Benitez just before Christmas.
Asked for his initial impressions, Moratti said: "Good, good, good. I liked it a lot. We won't give it a score out of 10, but to me it seemed that it went very well.
"From what I understood it was down to the spirit the players had before the game, so we came to this result automatically through the first training sessions Leonardo took, playing a professional game.
"We did well."
Finally, Moratti gave his opinion as to whether Inter can realistically compete for the Scudetto after a tough start to the season.
"We'll try," he smiled.
