Inter dominated the first half, but lost 2-1 to Udinese at San Siro with a Bruno Fernandes gem and Rodrigo Palacio howler.
This result takes the Friulani to joint seventh place with Milan and leaves the Nerazzurri in 12th.
Andrea Stramaccioni and assistant manager Dejan Stankovic returned to face Inter as opponents for the first time, but missed Luis Muriel and the suspended Maurizio Domizzi. Roberto Mancini reshuffled again with Yuto Nagatomo back from injury, though Hernanes and Jonathan were sidelined. The Nerazzurri were without a League victory since October 26 and lost their first game under Mancio, 4-2 away to Roma.
The last 12 Serie A meetings between these sides had only one draw and going into San Siro it was Udinese who were one point in front of their more prestigious rivals.
Thomas Heurtaux risked an own goal in the opening 80 seconds, while Orestis Karnezis palmed a dangerous cross off the head of Rodrigo Palacio.
Inter went incredibly close on 22 minutes, as Fredy Guarin rode a tackle to set up Mateo Kovacic, whose shot thumped the crossbar. The move continued and Heurtaux threw himself in front of Palacio to charge down the follow-up from six yards.
Gary Medel drilled wide from distance and Antonio Di Natale curled over the bar, as Udinese sat back and waited for rare counter-attacking opportunities. Emmanuel Badu’s diving header was straight at Samir Handanovic.
Just as it looked to be a frustrating goalless half, Mauro Icardi sprung the offside trap on a Guarin slide-rule pass and smashed in at the near post. It was his seventh goal of the season scored at San Siro.
After the restart, Inter wasted a golden opportunity to go three-against-one, as Dodo tried to set up Icardi rather than Guarin. Juan Jesus hooked down a corner from six yards only to see the shot charged down.
Di Natale’s snapshot was wide from distance, while a corner flashed past both Heurtaux and Danilo until the captain nodded over.
Dodo completely failed to cut out a cross-field pass for Di Natale, but was grateful for Handanovic’s save from point-blank range.
Udinese were pouring forward and got their equaliser thanks to a fantastic bit of skill and invention. Bruno Fernandes gathered outside the box, flicked it up with his first touch and volleyed in the second, his finish looping into the far top corner.
The game really came alive and Kovacic skimmed the upright from the edge of the box, Andrea Ranocchia performed practically a goalline clearance on Allan and Bruno Fernandes’ glancing header was off target.
Inter incredibly shot themselves in the foot, as Palacio’s terrible backpass was straight into the path of substitute Cyril Thereau, who dribbled round Handanovic to deposit into an empty net.
Ivan Piris sprinted after Guarin to charge down the shot as the Colombian pulled the trigger, while Handanovic used his leg to deny Thereau following another defensive error. Dodo finished off a nightmare performance by over-stretching and sustaining an injury.
Even Handanovic went up for the final corner and got his head to it, but Udinese were able to clear and secure the victory.
