(CNN) -- Andrea Pirlo played a starring role against his former club AC Milan to keep Italian champion Juventus in touch with the Serie A leaders Sunday.

The veteran midfielder scored a free-kick and hit the bar with another, allowing Giorgio Chiellini to volley what would be the decisive goal for a 3-1 lead.

AC Milan, down to 10 men by that stage after defender Philippe Mexes was sent off for protesting his initial booking, reduced the deficit through Sulley Muntari's second of the match at the end.

It left Juve in third place on goal difference behind Napoli, which also remained unbeaten following a 4-0 win at home to Livorno.

Both clubs trail Roma by two points, following the capital club's Saturday win at Inter Milan.

Former Inter midfielder Muntari gave Milan the lead inside 30 seconds, but Pirlo -- who spent a decade at the San Siro -- equalized after 15 minutes with a set-piece that goalkeeper Christian Abbiati could only deflect into the net.

Substitute Sebastian Giovinco put Juve ahead in the 69th minute from Arturo Vidal's pass, soon after his arrival on the pitch, and then Mexes' moment of madness was to prove vital for Milan as Chiellini immediately capitalized.

The defeat left the seven-time European champion languishing in 12th place, some 13 points adrift of Roma.

Napoli, like Juve, has six wins and a draw from seven matches, continuing new coach Rafael Benitez's fine start.

Former Real Madrid striker Gonzalo Higuain was again missing due to injury, but the Neapolitans had too much firepower for Livorno.
