Inter Milan slumped to another home defeat this time to Udinese who shot themselves to the top of Serie A level on points with AC Milan.
In a match which saw two penalties and also two red cards, it was Mauricio Isla’s 73rd minute penalty which settled a bad-tempered affair.
Javier Zanetti was sent off and conceded a penalty, which Julio Cesar managed to save before a final twist saw Udinese defender Damiano Feronetti received his marching orders for bringing down Diego Milito.
Still, Giampaolo Pazzini missed the resultant spot-kick as the former champions continue to struggle domestically.
The win puts Udinese joint top of Serie A on 27 points level with AC Milan and one point ahead of third-placed Juventus.
Inter remain in 15th place with a measly 14 points.
