There was also controversy at Juventus who beat Cesena 2-0
to stay unbeaten and go top with the help of a hotly-disputed late penalty.
That match saw Juventus captain Alessandro Del Piero's
frustrating season continue when he was taken off injured after just eight
minutes of yet another substitute appearance.
Colombian Victor Ibarbo scored a superb individual goal to
give Cagliari a 1-0 win at Catania, the Sardinians first victory since Davide
Ballardini became their third coach of the season.
Juventus lead the table with 29 points from 13 games, two
ahead of AC Milan, who won 2-0 at Genoa on Friday, and Udinese, who beat Inter
Milan 1-0 away on Saturday.
Serie A's two crisis teams clashed in Florence where the
hosts this week fined Alessio Cerci and Andrea Lazzari for a late night out and
Roma were still reeling from the Osvaldo incident, where he punched team mate
Erik Lamela after last week's defeat at Udinese.
Fiorentina, wearing black armbands in memory of former
Brazil captain Socrates who played for the club for one season and died earlier
on Sunday, were looking for their first win and goals under new coach Delio
Rossi.
They were quickly on top after Stevan Jovetic was hauled
back by Juan in the 15th minute.
The Brazil defender was sent off while the Montenegro
international coolly converted the penalty in the 15th minute for his sixth
league goal of the season.
Roma responded well but suffered another blow just before
halftime when Alessandro Gamberini headed in Riccardo Montolivo's corner to
make it 2-0.
The visitors went to pieces in the last quarter of an hour
when Fernando Gago was dismissed for a sliding tackle on Jovetic in the 77th
minute and Bojan Krkic followed nine minutes later for punching a goal-bound
shot off the line.
Uruguayan Santiago Silva converted the resulting penalty as
Fiorentina moved onto 16 points, one behind their ambitious but troubled
opponents whose Spanish coach Luis Enrique can look forward to a torrid week.
In Turin, Juventus struggled to break down a defiant Cesena
and lost Del Piero with a gashed forehead just after the hour.
It was doubly frustrating for the 36-year-old who had been
brought on in the 56th minute rather than in the last few minutes, as his been
more common this term under coach Antonio Conte.
Claudio Marchisio broke through in the 72nd minute with his
sixth goal of the season but Cesena were livid about Arturo Vidal's penalty,
which settled the match 11 minutes later.
Goalkeeper Francesco Antonioli punched away a cross but in
doing so caught Juventus forward Emanuele Giaccherini with his outstretched arm.
The referee awarded a penalty and sent off Antonioli, who
had to be replaced by defender Guillermo Rodriguez as Cesena had used up their
substitutions, amid furious protests from the disbelieving visitors.
The goal of the day was provided by Ibarbo who jinked his
way past two defenders and then cleverly rounded Catania goalkeeper Mariano
Andujar to give Cagliari a 1-0 win.
Bologna beat Siena 1-0 while Atalanta held Chievo 0-0 in
Sunday's other games.
