Emanuele Giaccherini struck deep into stoppages to sink a solid Catania side, putting Juventus nine points clear at the top of the table.
The Bianconeri welcomed back Nicolas Anelka and Paolo De Ceglie to the bench, though Martin Caceres, Nicklas Bendtner and Simone Pepe remained sidelined with Arturo Vidal suspended. Mirko Vucinic and Sebastian Giovinco returned to the starting XI after they were rested for the 2-0 Champions League win over Celtic. Catania were eager to recover from their 3-2 home defeat to Inter, a tie they were winning comfortably 2-0, though Nicola Legrottaglie continued his two-match ban with Gonzalo Bergessio and Marco Capuano injured.
Giorgio Chiellini only skimmed an Andrea Pirlo free kick and Mariano Andujar palmed a Mirko Vucinic effort out for a corner.
Francesco Lodi tried from distance, but swung it just past the far post. Neither side could find a way through, so there were more often than not long-range attempts from Lodi and Leonardo Bonucci.
Claudio Marchisio’s angled drive was deflected wide and Vucinic nodded over from the corner.
Juventus finally made a dent in the Elefantini when Sergio Almiron and Giuseppe Bellusci got in each other’s way trying to clear a Sebastian Giovinco cross and Vucinic took advantage, thumping the base of the post.
Catania Coach Rolando Maran was sent off after just 36 minutes for dissent. Alejandro Gomez got on the end of a long ball, but the angled drive was smothered by Gigi Buffon.
Andujar had his palms stung by a long-range Paul Pogba screamer, but there were still precious few scoring opportunities for either side.
Andrea Pirlo was bundled off the ball for a counter-attack, though Castro wasted the finish by firing wide.
Juve went so close on 73 minutes, as Pirlo’s low free kick was charged down by Pablo Alvarez on to the feet of Marchisio, but at full stretch the midfielder toe-poked the follow-up inches wide of the back stick.
Alessandro Matri nodded over, while in the final minute Emanuele Giaccherini was booked for simulation after going down in the box.
It seemed to be heading for a draw, but Juventus scored in stoppages. Pogba brilliantly hooked a cross down the right and put it back into the centre, where Giaccherini was quicker to react than anyone and bundled over the line from close range.
Fabio Quagliarella should’ve made it 2-0 on the counter, but prodded it straight at the goalkeeper.
