Match ends, Inter Milan 2, Napoli 2.
Inter Milan scored a dramatic injury-time equaliser to grab a point and deny Napoli boss Rafael Benitez a victory against his former side.
Hernanes rescued a draw with a 91st-minute header following Dodo's cross
Jose Callejon's angled shot from 15 yards out put the visitors ahead with just 12 minutes left at the San Siro.
Inter levelled through substitute Fredy Guarin's close-range finish before Callejon hit an 89th-minute volley but Hernanes then added to the late drama.
Former Liverpool and Chelsea boss Benitez, who was in charge of Inter for six months in 2010 before being sacked, guided Napoli to third place in Serie A last season.
However, this result means they are seventh in Serie A, eight points behind leaders Juventus, while Inter are ninth with only one win in their last five league matches.
Inter head coach Walter Mazzarri was sent to the stands after running onto the pitch to celebrate his side's first goal.
