Juventus and AC Milan were both held to draws to keep things tight at the Serie A summit as only one of the top seven teams managed to win on Sunday.

Sixth-placed Roma's 4-0 thrashing of fifth-placed Inter Milan was the lone success for the leading teams.

Leaders Juve were held 0-0 at home to lowly Siena while second-placed Milan shared a goalless stalemate with seventh-placed Napoli.

Udinese, in third, and Lazio, fourth, both lost in a terrible day for the country's top brass, although it wasn't a great day for entertainment either with four scoreless stalemates.

At the San Siro, Milan had Zlatan Ibrahimovic sent-off for violent conduct but still came closest to winning.

Robinho wasted a glorious chance to give Milan the lead from Ibrahimovic's flick when he was through one-on-one with goalkeeper Morgan De Sanctis but he screwed his effort wide of the upright.

Midway through the second half Ibrahimovic was given his marching orders for petulantly and needlessly slapping Salvatore Aronica, who responded, almost comically, by slapping Antonio Nocerino, behind whom the big Swede had been standing when he launched the intital assault.

Aronica, however, escaped punishment.

Playing against 10-men Napoli created a great chance when Ezequiel Lavezzi picked out Edinson Cavani at the back post but his header was woeful.

But Milan suddenly proved more dangerous on the counter and Urby Emanuelson set up Robinho only for De Sanctis to deny the Brazilian.

Despite their reduced numbers, the team coped quite well and claimed a draw. However, the team must now do without Swedish star Ibrahimovic for their next three league outings.
