The hosts went into their match against Juventus in good form, after scoring five goals in a cup win over Ternana, before claiming a 2-0 win over Empoli in their Serie A opener.
However, they were no match for the Italian champions and fell to a 2-0 defeat in Turin.
They are still able to call on the services of veteran striker Antonio Di Natale, who has scored all seven of their goals so far this season.
Visiting the Stadio Friuli on Sunday is a Napoli side who have endured a difficult opening to the new season.
Their fans were already frustrated by the team's failure to reach the group stages of the Champions League, and last weekend's 1-0 defeat at home to Chievo did little to improve the mood.
However, they do come into the match with a win under their belt, after coming from behind to beat Sparta Prague in the Europa League on Thursday evening.
Possible starting lineups
Udinese: Karnezis, Heurtaux, Danilo, Bubnjic, Widmer, Guilherme, Allan, Kone, Pasquale, Muriel, Di Natale
Napoli: Cabral, Maggio, Koulibaly, Albiol. Zuniga, Inler, Gargano, Mertens, Hamsik, Callejon, Higuain
Sports Mole says: 1-1
