- Fabio Borini scores twice as Roma thrash Inter Milan 4-0 in Italy's Serie A
- Four of Sunday's matches end scoreless with Juve and Milan both drawing
- Juventus remain top by a point from Milan with Udinese back in third place
Inter Milan's Serie A title hopes suffered a huge setback on Sunday after they were thrashed 4-0 at Roma, while top two Juventus and AC Milan were both held to goalless draws.
Roma took a 13th minute lead when Juan headed home a Francesco Totti corner and Fabio Borini doubled their lead when firing a shot through the legs of goalkeeper Julio Cesar.
Former Chelsea striker Borini added his second four minutes after the interval when racing onto Juan's pass to again shoot through Cesar's legs.
And Bojan Krkic completed a miserable return to the Stadio Olympico for Inter coach Claudio Ranieri when he added a fourth goal a minute from time.
The result leaves Inter in fifth place in the table, nine points off the lead, with Roma a further two points back in sixth position.
To complete a perfect afternoon for Roma, they confirmed after the match that in-demand midfielder Daniele De Rossi had signed a five-year contract extension with the club.
Juventus remain top on 45 points, and are still unbeaten after 21 games, despite a disappointing 0-0 draw at home to lowly Siena.
They stay a point ahead of second-placed Milan, with a game in hand, after the Rossoneri were held 0-0 at home by Napoli.
Milan will be thankful for the point after playing the final 20 minutes with 10 men following the dismissal of Zlatan Ibrahimovic for slappig Salvatore Aronica.
On a day when Roma were the only top-seven team to secure three points, third-placed Udinese failed to close the gap after falling to a 3-2 defeat at Fiorentina.
That result leaves Udinese four points behind Juventus, with Lazio still in fourth after their 3-2 loss at Genoa.
Meanwhile, in Germany, Freiburg remain bottom of the Bundesliga despite recovering to earn a 2-2 home draw with fifth-placed Werder Bremen, for whom Claudio Pizzaro scored both goals.
Sunday's other match saw Albanian midfielder Odise Roshi score the only goal as Cologne defeated Kaiserslautern 1-0.
