Produced a one-handed save from Stankovic soon after the Serb had struck the first goal of the game and later had to get down low to keep out a free-kick from the same player.
Never will the centre-back have hit a ball with his left foot quite as sweetly as he did to equalise in the 21st minute. He then put in his shift at the back to help keep Inter out.
His unpredictability meant it was a very tough afternoon for Maicon, who was forced back into the right back slot more often than he is used to.
Largely stood his ground in the wake of Inter's possession, more than playing his part as the back three stood firm and conceded few real chances.
Was slow to react as Thiago Motta approached in the build-up to Inter's goal, but later managed to wrap the game up having also come close with a free-kick.
Almost got in ahead of Castellazzi when he broke the offside trap superbly early in the second half and regularly found holes in Inter's rearguard.
Is he the under-rated heart of Udinese's recent run? His work down the right kept Chivu honest throughout and his return pass to Di Natale almost put the skipper in for a second.
Used his speed advantage in the battle with Zanetti and regularly managed to force the Inter skipper onto the back foot.
Got on with his usual job in the centre despite picking up a knock in the first half. The rock around most Friulani attacks.
A. Di Natale
Hit a magnificent free-kick to send his side ahead and got into three more great goalscoring positions as he ran the Inter defence ragged.
Went into the game with goals in his last four outings, and could have made it five with his early header. Did more than enough to catch Massimo Mmoratti's eye with the transfer window still open.
Could have done much better as Zapata's equaliser went through his hands, though no blame could be apportioned to him for the other two goals and he made a good save from Domizzi's free-kick too.
Had a tough job on to keep on top of Asamoah, who worked well in tandem with Armero to cause the Tractor and Maicon all sorts of headaches.
Looked shaky throughout and rarely had any answer to the front two. Then made things worse by keeping Domizzi onside to make it 3-1.
Not his usual commanding self of late, and he continued in that vein today. Outdone too often by the skill and pace of Sanchez and Di Natale.
Too often allowed Isla and Pinzi to get time and space on the right as Udinese made plenty of chances.
Spent more time going backwards than forward as his usual game was compromised by the adventure shown by Armero.
Did well to win the ball and set up Stankovic for the opener, but couldn't continue his fine start and faded. Replaced on 71 minutes.
Scored one and came close to two more as he carried the fight in the first half. Faded in the second, but deserved more for his performance.
Seemed to have much less time and space than usual and made less of an impact as a result. Udinese did a good job on him today.
Finally getting his much sought after run up front, but he was given little service in the centre as Inter struggled to find the last pass.
Went missing all too often as Inter couldn't ask enough questions of Udinese's backline after going behind.
