Sunday's 3-0 win over their city rivals has helped to secure the Rossoneri coach's position, according to the club's honorary president.
AC Milan honorary president Silvio Berlusconi said coach Sinisa Mihajlovic can breathe easy again, after guiding his side to an impressive 3-0 win over city rivals Inter.
Mihajlovic has had to deal with constant speculation regarding his future because of the Rossoneri's fluctuating form in his first season at San Siro.
Before the derby, Milan had won just four out of 11 Serie A games since the start of November, but with the pressure increasing on the coach after a 2-2 draw away to Empoli, his players delivered the best possible response against their co-tenants.
