Parma have had a poor start to the season and only managed a goalless draw against Chievo at the weekend.
“The many unfavourable episodes have determined our current situation, and the results have not gone our way,” Leonardi explained to Sky.
“I am not thinking about sacking Marino, and believe that the side can get out of this situation with the help of our coach.
“We need to resolve our goal problems because we are able to create many chances, but convert very few.”
