Udinese kept the pressure on league leaders Juventus with a nervy 1-0 win over Palermo thanks to talismanic captain Antonio Di Natale.
Di Natale, 34, made a goalscoring return from injury to secure the three points but could, and probably should, have won more comfortably.
Udinese were particular wasteful in front of goal, missing numerous late chances to kill the game on the counter attack.
They now trail Juventus by just one point but can be joined by Lazio on 18 points if the capital-based club win at Cagliari on Sunday night.
Udinese first opened up Palermo when Giampiero Pinzi got into the box but with only goalkeeper Alexandros Tzorvas to beat he opted to try to pick out Di Natale instead but fluffed his pass.
Di Natale hit the bar with an acrobatic volley from the edge of the box but was called for offside.
Mauricio Isla picked out Kwadwo Asamoah from the right but the Ghana midfielder’s shot was well saved by Tzorvas.
The goal came on 38 minutes when Dusan Basta picked out Di Natale, who was right on the limit of offside but scored with a volley as he fell sideways.
Udinese could have scored again when Di Natale was free in the box but Pablo Armero’s pass made the striker check his run, his first touch was poor and then his inventive chip flew wide.
Udinese played cleverly on the counter after the break and Di Natale’s volley from Isla’s cross went just past the upright.
Armero then picked out Di Natale, who shot into the side-netting before returning the favour only for the Colombian wing-back to crash his effort off the post.
Palermo’s best chance fell to Israeli forward Eran Zehavi but his finish was weak and Samir Handanovic saved easily.
Almen Abdi was the chief culprit for Udinese late on, blazing high when one-on-one with Tzorvas and then firing into the side-netting having rounded the keeper.
