Fassone says the club's spirit has returned.
"With Mancini we can start talking about a mini-cycle," the director general to Radio Rai.
"We've won eight points in our last four matches, there's renewed enthusiasm.
"When we asked about his availability in November, Mancini showed himself to be a Coach who likes to know the financial situation.
"We're doing things together, we're trying to build something important within certain parameters, there are more restrictions than in the past.
"Mancini has never made any secret of wanting to play in a certain formation with new players, we still have 20 days to rebalance the books after the expenditures we've made."
