In Siciliy, home side Catania were left feeling hard done by after Gonzalo Bergessio's effort in the first half was wrongly ruled out for offside.

And the locals were further aggrieved when defender Giovanni Marchese was sent off for a second yellow after Vidal's goal.

To make matters worse for Catania, Nicklas Bendtner appeared to in an offside position in the build-up to Juventus' 57th-minute winner.

The win maintains Juventus' lead at the top of the table with 25 points and extends their unbeaten run in the league to 48 games.

The only goal of the game arrived in typically controversial circumstances when Mario Vucinic picked out Bendtner only for the Danish striker to shoot tamely at Mariano Andujar.

Vidal pounced on the rebound but the home crowd were soon incensed when the replay showed Bendtner was in a clear offside position.

Inter Milan, meanwhile, stretched their winning streak to five matches with a 3-1 victory over Bologna.

Goals from Andrea Ranocchia and Esteban Cambiasso either side of Diego Milito's strike were enough to render Niccolo Cherubin's 58th-minute header for the home side inconsequential.

Ranocchia headed in Cambiasso's cross on 27 minutes before the Argentine provider turned goal scorer to put the visitors 3-1 up six minutes after Cherubin's reply.

Bologna would eventually pay for their wastefulness in front of goal as a string of long shots missed their mark in an entertaining encounter.

In Rome, Udinese fought back from two goals down to beat Roma 3-2, with Antonio Di Natale scoring the winner from the spot in the 88th minute.

Erik Lamela scored twice in three first-half minutes to get Roma off to a brilliant start but a goal to Udinese from Maurizio Domizzi ensured the scoreline read 2-1 at half-time.

Di Natale equalised for Udinese in the 50th minute and then clinched victory when he converted a penalty after Leandro Castan fouled Roberto Pereyra in the box.
