Juventus' lead at the top could come under threat today when they are expected to be without three key midfielders, including Andrea Pirlo, at home to in-form Udinese.
The champions, on 45 points, have a three-point lead over Napoli, who moved back into second place in unexpected fashion on Thursday, when the Italian federation overturned a two-point deduction for suspected match-fixing.
Lazio dropped to third, equal on points, while Inter Milan are fourth on 38.
However, Juve's hopes of keeping the chasing pack at bay could be dealt a blow even before Udinese, whose striker Antonio Di Natale has recently taken his league tally to an impressive 14 goals, visit Turin.
Italy international Pirlo (calf) and Chilean winger Arturo Vidal (ankle) added to coach Antonio Conte's woes when they missed training on Thursday.
Claudio Marchisio, who missed last week's 1-1 draw at Parma because of a knee injury, also remains doubtful as he continues to work his way back to match fitness.
