Udinese have a 1-0 half-time lead over Lazio in this afternoon's Serie A encounter at the Stadio Friuli.
The hosts made the breakthrough with just eight minutes played as Antonio Di Natale scored from the penalty spot following Luis Pedro Cavanda's foul on Maicosuel.
Lazio had a chance level the match midway through the half, but Sergio Floccari could only blaze his effort high over the crossbar after getting into a good position inside the box.
Floccari came close again towards the end of the half, although this time his low drive was kept out by Udinese goalkeeper Etrit Berisha.
