Juve and Roma ease to victories
Juventus beat Sampdoria 4-2 on Saturday to extend their winning Serie A run to 12 games and stay eight points clear of Roma, who beat Livorno.
Arturo Vidal scored twice, including a penalty, and Fernando Llorente and Paul Pogba were also on target for the hosts.
Andrea Barzagli's own goal gave the visitors hope and lively on-loan Juventus striker Manolo Gabbiadini was also on target for Sampdoria.
However, Juve picked up the three points to maintain their eight-point advantage at the top over Roma, who beat Livorno 3-0 earlier in the day.
Goals from Mattia Destro, Kevin Strootman and Adem Ljajic marked a dominant performance from the Giallorossi as they moved five points clear of third-placed Napoli, who go to Bologna on Sunday.
Livorno, however, failed to get going at the Stadio Olimpico and remain four points from safety after a fifth successive defeat.
