Leonardo has won all but one of his matches in charge since replacing Rafa Benitez and climbed up to third place with a game in hand.
"The confrontation between Inter and Roma is a tradition now with so many recent examples at the highest level. It will be a great match, as intense as always and can give important signals for this season.
"I am very satisfied with the positive run of results, because Serie A is truly very difficult," said Leonardo.
"I knew this team could do well and it has. I also believe we can do even better. I do really like strikers.
"If the system didn't really work in that occasion, it was only because we missed that link in midfield. The fact there were so many strikers was not the problem. Milito is naturally trying to find his form after a long injury."
