Defending champion Juventus hosts Napoli on Saturday (Sunday AEDT) in a clash of two unbeaten teams at the top of the Serie A standings.
Juventus striker Fabio Quagliarella, who left Napoli in 2010, is relishing the prospect of the game, with both teams on 19 points, but says it's too early to talk about games which will decide the season.
Juventus is looking to make it 47 games unbeaten in Serie A, although Napoli's victory in the Italian Cup final inflicted Juve's only loss last season.
The defending champion has been hit by Gianluigi Buffon's injury - which forced him to sit out Italy's World Cup qualifier against Denmark - being deemed more serious than first thought.
Brazilian striker Barreto will remain at Torino for the 2013-2014 season after the Serie A club renewed its co-ownership arrangement with Udinese.
