The Serie A club's sporting director says that there is no chance that the Nerazzurri coach will leave regardless of where they finish in the Scudetto race in 2013-14
The Nerazzurri chief believes that, despite their current fifth position, the team have made a lot of progress under the former Napoli boss, who took over in 2013.
"He works 24 hours a day," Ausilio told La Gazzetta dello Sport. “He follows all the movements of the team.
"Mazzarri is part of the foundation. You can already see a growing team, a different game, a solid defence. Despite our ranking, it looks like that. Mazzarri will remain, regardless of where we finish."
The sporting director is confident that the club can hold on to their main assets, while he also hints that new arrivals could be on their way to San Siro but stresses that the Nerazzurri will not splash out on more than they can afford.
"Mazzarri has worked wonders with Rolando, we want to keep him. [Andrea] Ranocchia we will talk with at the end of the season but I wouldn't rule out a renewal.
"With [Fredy] Guarin and [Ricky] Alvarez we are in a good place. The heroes from the treble? We will speak with everyone at the end of the season, just as we did with [Walter] Samuel last year when he renewed in five minutes flat but who knows what will happen. [Diego] Milito could give experience and quality even if not as a starter.
"There is just one prerequisite: that the parameters do not exceed the current ones. As stated by [owner Erick] Thohir, the total salary cannot exceed €70-80m (£58.4-66.7m)."
