The Argentine midfielder admits Mazzarri has brought a new energy with him from Napoli.
"The Coach is very hungry for success, as we all are, so that is very important. I don't like talking about tacticians, as if you say something nice then people think you're trying to make a good impression, while criticism creates chaos," he told Libero.
"The most important thing is that the squad is able to assimilate all his tactical ideas so we can understand each other. We need clear ideas and for everyone to be working in the same direction. Mazzarri achieved that elsewhere and now we hope he can do it at Inter too."
