Leonardo dismissed speculation that the club's boss could be replaced as the club fights through a difficult spell.
AC Milan have never considered sacking Gennaro Gattuso and do not plan to part with the head coach, insisted sporting director Leonardo.
Milan head coach Gattuso is reportedly under pressure following a five-match winless streak, with the Serie A side without a goal in their previous four league games.
It is Milan's longest spell without a league goal since 1984 as pressure mounted on Gattuso ahead of Saturday's visit of SPAL, however, Leonardo dismissed speculation that the 40-year-old boss could be replaced.
"We never thought about changing Gattuso," Leonardo told reporters as Milan now sit fifth in the Serie A standings after getting a much needed win against SPAL, and the break of Higuain's goal drought. "We can deny this general situation.
"We need a bit of understanding to fix this situation, we're not going to buy 10 players and suddenly fix everything.
"There is no plan to change Gattuso, and Milan have not contacted anyone else."
Following the clash with SPAL, Milan will now get time to regroup.
The club don’t play again until the middle of January and will get the chance to earn some silverware on their return to action with a Supercoppa final against league leaders Juventus.
Milan will also get the chance to add to their roster ahead of that match, though the club could face a struggle to hold on to Gonzalo Higuain, with the forward being linked with a move to Chelsea this winter.
