ROME, Oct. 28 (Xinhua) -- Inter Milan proved they are serious contenders for the Scudetto this season after they beat Bologna 3-1 to move within four points of the Serie A leaders Juventus on Sunday.
Andrea Ranocchia gave the visitors the lead in the 27th minute before Diego Milito added a second just after the half-time break.
Nicolo Cherubin replied immediately, but Esteban Cambiasso scored his first goal of the season minutes later to seal Inter's fifth consecutive win.
Inter head coach Andrea Stramaccioni shocked many by switching Inter to a three-man defence, but has notched up a remarkable series of results.
"I am proud to have played my part, but if a team wins eight games away from home then it means the players are motivated and well set out," he said.
"At least it shows the club president didn't do something crazy by hiring me," he joked.
Napoli squeezed past Chievo 1-0 thanks to a goal from Marek Hamsik, and returned to second spot, three points behind Juventus.
Udinese turned the tables on Roma at the Stadio Olimpico, recovering from going two goals down by picking up a valuable three points on the road with a 3-2 win.
Two goals in two minutes from Erik Lamela appeared to have put the Giallorossi on the way to victory, but they suddenly stopped playing, allowing Udinese to hit back at them.
Maurizio Domizzi pulled a goal back before half-time and Antonio Di Natale brought them level early in the second half. Di Natale then scored the winner from the penalty spot and Panagiotis Tachtsidis completed Roma's self-destruction by earning a red card in stoppage time.
Roma head coach Zdenek Zeman blamed "a lack of concentration" and the referee for his side's loss.
"It has been a bad weekend for referees. People say they don't decide tournaments, but I think on the whole they really can," he said.
His Udinese counterpart Francesco Guidolin admitted even he didn't think Udinese could come back to win.
"It is right to be satisfied with the comeback and the result. We were on the edge of the precipice after 20 minutes, while before that I had believed we could do well here even without several key players," he said.
"I know the qualities of my men and that we could be competitive, but to be frank after 20 minutes I too thought this was going to be a bad night," he said.
Fiorentina needed two wonder goals to see off nine-man Lazio 2-0 in a game riddled with controversial refereeing decisions.
Fiorentina's victory sees them climb into fifth place in the league table, halving the six-point advantage of the capital club, who slip to fourth.
Daniele Dessena scored the only goal of the game as Cagliari claimed their third successive 1-0 win away to Sampdoria.
Parma rewarded boss Roberto Donadoni's decision to commit his future to the club as three second-half goals saw them to their first away victory of the season, 3-1, at 10-man Torino.
Atalanta overcame the dismissal of Federico Peluso to hold off the challenge of Pescara in a 0-0 contest at the Stadio Adriatico.
In an earlier kick-off of the day, Juventus scored a controversial 1-0 win at Catania.
After the hosts had a goal disallowed in the 25th minute, and the Sicilians' owner and president Antonio Pulvirenti was sent away from the bench, the home side struggled to maintain a level head and Juve took advantage.
Vidal scored the only goal of the game 12 minutes after the interval, which, unlike Catania's effort, should have been disallowed and it was enough to earn the Bianconeri all three points.
