Roberto Mancini suffered his second straight defeat as coach of Inter Milan after a shock 2-1 reverse to Udinese that left his side in 12th spot in Serie A on Sunday.
A week after a 4-2 defeat away to Roma, Inter welcomed former handler Andrea Stramaccioni back to the San Siro for the first time since his sacking at the end of last season.
Udinese were looking to end a five-game winless streak, and it was 38-year-old Stramaccioni who walked away with the plaudits after a composed and determined performance by the northerners.
Mauro Icardi gave Inter a first-half lead on the stroke of half-time.
But Bruno Fernandes levelled on the hour before Frenchman Cyril Thereau, who replaced Antonio Di Natale on 64 minutes, gave Udinese the lead seven minutes later.
Inter battled to pull level but chances were few and far between. Home `keeper Samir Handanovic moved upfield and got his head to the last corner of the game.
It was Udinese`s first win since a 2-0 home defeat of Atalanta on October 26 and moves Stramaccioni`s side up to eighth, 14 points behind leader Juventus but level with seventh-placed Milan.
Inter remain 12th, 18 points off the pace and now nine behind third-placed Genoa in the third and last Champions League qualifying spot.
