AC Milan chief Marco Fassone insists they're happy with the early impact of coach Rino Gattuso.
Gattuso oversaw his first win since being appointed with victory against Bologna on the weekend.
Fassone stated: "When you take these kinds of decisions you do not know what will happen. We made this decision because we saw that we behind compared to our project. We hope we were right.
“There is a good feeling between Mirabelli and Gattuso and I am convinced that this relationship will be useful to Milan.
“We hope he [Gattuso] isn't a gamble, because this wasn't a bet for us. In the previous weeks we had talked with Mirabelli about it for a long time, he followed him closely in the weeks preceding Montella's sacking.
“He's not a novice Coach, nor is he the first player promoted to coach the first team.
“We hope it's not a gamble and that Rino can succeed in this dream he is experiencing.
“The Coach always shows all his passion, both in euphoria and bitterness. He was very fired-up last night, and there's a wonderful relationship between him and the team.
“This Milan may lack other things but certainly not girt and determination."
