( CNN ) -- Udinese have gone top of the Italian Serie A table on goal difference from Lazio after captain Antonio Di Natale was again on target in a 2-1 victory over Siena on Sunday . With previous leaders Juventus seeing their match against Napoli called off because of torrential rain , Udinese , Lazio and Milan all exploited the situation with wins , dropping Juve to fourth place . Udinese took the lead after just 54 seconds against Siena , when Dusan Basta prodded the ball home from close range . And the prolific Di Natale doubled the advantage in the 64th minute when he cut inside a defender to finish Pablo Armero 's long ball . Siena pulled a goal back 13 minutes from time when Francesco Bolzoni fired home Emanuele Calaio 's header on the half-volley , but the home side held on to move onto 21 points from their 10 games . Lazio are level on point , but have just a single goal inferior goal difference following a 1-0 home win over Parma . Giuseppe Sculli poked home the winner with just five minutes remaining to leave Edy Reja 's side firmly in the championship race . However , the performance of the day came from Milan , who are ominously just a point behind in third position after thrashing Catania 4-0 . Zlatan Ibrahimovic opened the scoring with a seventh minute penalty after Davide Lanzafame fouled Robinho in the area . Brazilian striker Robinho then helped himself to the second goal in the 24th minute , curling the bal home after Ibrahimovic had sent him clear on the left wing . The same two players combined again for a 69th minute third goal , with Robinho 's strike being bundled over the line by back-tracking defender Francesco Lodi . And Gianluca Zambrotta added the icing on the cake for Milan three minutes later when he was on hand to score after Alberto Aquilani 's free-kick had been fumbled .
Udinese have gone top of Italian Serie A after a 2 - 1 home victory over Bologna . Lazio are level on points after beating Roma 1 - 0 while Milan win 2 - 1 and are third . Juventus are now down in fourth position after their match at Napoli was abandoned .
