Suso had looked set to be AC Milan's match-winning hero with two goals, before Perisic pounced in injury time.

Ex-Liverpool winger Suso curled home Milan's opener before Antonio Candreva smashed in an equaliser.

Suso scored again from a jinking run but Perisic turned home a corner from close range to deny Milan the chance to go 11 points above their rivals.

Inter have claimed nine points from behind in Serie A this season, more than any other side

Former Lazio boss Piolo took charge of a Nerazzurri game for the first time, having been named Frank de Boer's replacement during the international break.

A derby defeat would have been the worst start imaginable, especially one that would have left them 11 points behind their rivals.

But Inter deserved their draw, with Candreva's first equaliser a brilliant 25-yard effort, and they took risks in the end, with goalkeeper Samir Handanovic coming up for the corner which Perisic converted.
