Elsewhere, Sampdoria, also in the midst of a similar slump in form, were narrowly beaten by Parma, while a struggling Udinese picked up a slender win over Pescara
|Cagliari made it two wins on the bounce on Sunday, as they dug out a 1-0 win over Bologna at the Is Arenas.
The winning goal came on 61 minutes - Radja Nainggolan, linked with a summer transfer to Juventus, pounced on a loose ball from Albin Ekdal, and fired home.
The result means the Sardinians move up to seventh place, while Bologna, without a victory in four, are now 16th.
|Atalanta came back from a goal down to eventually overcome Siena 2-1 at the Azzurri d'Italia and end a sequence of three straight defeats.
It took an hour for the match to kick into action, as Angelo's cross from the right flank was met by Reginaldo to put the Bianconeri in the lead.
However, just four minutes later, Luca Cigarini placed Atalanta on level terms from a free kick, which sailed into the top right corner.
And despite Carlos Carmona's red card moments later, the Bergamese outfit went onto find the winner through Giacomo Bonaventura from the edge of the box.
They now climb to 13th in the standings but Siena, having suffered a third consecutive loss, remain rooted to the bottom.
|Fiorentina's early-season momentum seems to have dried up after they failed to break down Chievo in a 1-1 draw at the Bentegodi on Sunday.
Seventeen minutes into proceedings, Luciano's left-wing pass was finished off with aplomb by Cyril Thereau, who kept his goalscoring form up with a powerful strike into the corner of the net.
However, Vincenzo Montella's side were not behind for long. Gonzalo Rodriguez capitalised from a corner with Stefano Sorrentino struggling to command his box.
The Flying Donkeys are now 17th, but Fiorentina fall to sixth spot and 12 points behind pace setters Juventus.
|Palermo were left to rue their failure to convert an array of chances on Sunday, as they could only muster a 0-0 draw with Torino.
Jasmin Kurtic and Josip Ilicic were the most guilty parties at the Renzo Barbera, fluffing their lines on more than one occasion, although their efforts were not helped by the goalkeeping exploits of Jean-Francois Gillet.
The Rosanero may not have won but are now unbeaten in their last three under Gian Piero Gasperini, though they remain in 19th position. Torino sit in ninth.
|Parma stopped a run of five matches without a win on Sunday after surviving a late scare to defeat Sampdoria 2-1 at the Tardini.
The home team took the initiative on 36 minutes from the penalty spot. Sergio Romero was shown a straight red card for bringing down Jonathan Biabiany in the box, allowing Amauri to net from 12 yards out.
Eight minutes after the break, Amauri scored his second of the afternoon thanks to Aleandro Rosi's cross. It proved to be enough for the Gialloblu, despite Eder's spot kick nine minutes from time.
They now sit in 11th place but Ciro Ferrara's men stay eighth in Serie A, although their fine start to the campaign has since been followed by three straight reverses.
|Udinese's underwhelming start to the season took a turn for the better, as they held on for a 1-0 victory over Pescara on Sunday.
However, their cause was not helped in the first half by Danilo, who was shown a second yellow and subsequent red for his foul on Juan Fernando Quintero on the edge of the box.
Still, the Zebrette got their just rewards on 53 minutes through Maicosuel. Pablo Armero's cross deflected into the path of the former Hoffenheim striker and he made no mistake with the finish.
The hosts move to 12th but the Delfini's recent renaissance looks to have ended, as they flounder in 18th spot.
|In the last of the week's fixtures on the peninsula, Genoa and Roma made for a fitting end to the round as the Giallorossi turned around a two-goal deficit to eventually win 4-2 at the Marassi.
Juraj Kucka gave the Ligurians the lead on seven minutes, wrapping up good hold-up play from Marco Borriello, before the Slovakian set up Bosko Jankovic to double his side's lead inside just 15 minutes.
Little did they know but a Roman comeback was on the cards. Francesco Totti took full advantage of a cross at the far post, before a pinpoint cross from Ivan Piris was drilled in by Pablo Osvaldo on the stroke of half-time.
The capital outfit went into the second period with the momentum and Osvaldo was at it again - this time heading home Alessandro Florenzi's corner. Eric Lamela then secured victory late on.
Roma jump to fifth place in Serie A, having made it two wins in a row, but Genoa sit in 10th.
