A brace from Antonio Di Natale and a goal from Luis Muriel saw the Nerazzurri begin 2013 in disastrous fashion, but they were left furious by the performance of referee Antonio Giannoccaro, who sent off defender Juan Jesus and booked Rodrigo Palacio for diving.
“We had a good first half, but the 3-0 result is unfair and does not reflect the real game,” Stramaccioni told reporters after the game.
“Up until the Juan Jesus red card, it was a totally different match. We certainly aren’t fortunate when it comes to refereeing decisions, as once again today there was an incident.
“Palacio is a very fair player and he should not have been booked for simulation. Maurizio Domizzi put his hand on his neck and unbalanced him, so for me that is a penalty and a red card.
“I don’t think the referees have anything against Inter, but you have got to give a penalty like that. I’d say Inter were excellent for 65 minutes, but Jonathan wasted an incredible chance and then Udinese ran away with it.”
The defeat leaves Inter in fourth place in the Serie A table, nine points behind leaders Juventus having played one game more.
